PRODUCT SAFETY SERVICING GUIDELINES FOR AUDIO-VIDEO PRODUCTS

IMPORTANT SAFETY NOTICE

This manual was prepared for use only by properly trained audio-video service technicians.

When servicing this product, under no circumstances should the original design be modified or altered without permission from Zenith Electronics Corporation. All components should be replaced only with types identical to those in the original circuit and their physical location, wiring and lead dress must conform to original layout upon completion of repairs.

Special components are also used to prevent shock and fire hazard. These components are indicated by the letter “x” included in their component designators and are required to maintain safe performance. No deviations are allowed without prior approval by Zenith Electronics Corporation.

Circuit diagrams may occasionally differ from the actual circuit used. This way, implementation of the latest safety and performance improvement changes into the set is not delayed until the new service literature is printed.

CAUTION: Do not attempt to modify this product in any way. Never perform customized installations without manufacturer’s approval. Unauthorized modifications will not only void the warranty, but may lead to property damage or user injury.

Service work should be performed only after you are thoroughly familiar with these safety checks and servicing guidelines.

GRAPHIC SYMBOLS

The exclamation point within an equilateral triangle is intended to alert the service personnel to important safety information in the service literature.

The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the service personnel to the presence of noninsulated “dangerous voltage” that may be of sufficient magnitude to constitute a risk of electric shock.

The pictorial representation of a fuse and its rating within an equilateral triangle is intended to convey to the service personnel the following fuse replacement caution notice: CAUTION: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ALL FUSES WITH THE SAME TYPE AND RATING AS MARKED NEAR EACH FUSE.

TIPS ON PROPER INSTALLATION

1. Never install any receiver in a closed-in recess, cubbyhole, or closely fitting shelf space over, or close to, a heat duct, or in the path of heated air flow.

2. Avoid conditions of high humidity such as: outdoor patio installations where dew is a factor, near steam radiators where steam leakage is a factor, etc.

3. Avoid placement where draperies may obstruct venting. The customer should also avoid the use of decorative scarves or other coverings that might obstruct ventilation.

4. Wall- and shelf-mounted installations using a commercial mounting kit must follow the factory-approved mounting instructions. A product mounted to a shelf or platform must retain its original feet (or the equivalent thickness in spacers) to provide adequate air flow across the bottom. Bolts or screws used for fasteners must not touch any parts or wiring. Perform leakage tests on customized installations.

5. Caution customers against mounting a product on a sloping shelf or in a tilted position, unless the receiver is properly secured.

6. A product on a roll-about cart should be stable in its mounting to the cart. Caution the customer on the hazards of trying to roll a cart with small casters across thresholds or deep pile carpets.

7. Caution customers against using a cart or stand that has not been listed by Underwriters Laboratories, Inc. for use with its specific model of television receiver or generically approved for use with TVs of the same or larger screen size.

8. Caution customers against using extension cords. Explain that a forest of extensions, sprouting from a single outlet, can lead to disastrous consequences to home and family.

SERVICE INFORMATION

While servicing, use an isolation transformer for protection from AC line shock. After the original service problem has been corrected, make a check of the following:

FIRE AND SHOCK HAZARD

1. Be sure that all components are positioned to avoid a possibility of adjacent component shorts. This is especially important on items transported to and from the repair shop.

2. Verify that all protective devices such as insulators, barriers, covers, shields, strain reliefs, power supply cords, and other hardware have been reinstalled per the original design. Be sure that the safety purpose of the polarized line plug has not been defeated.

3. Soldering must be inspected to discover possible cold solder joints, solder splashes, or sharp solder points. Be certain to remove all loose foreign particles.

4. Check for physical evidence of damage or deterioration to parts and components, for frayed leads or damaged insulation (including the AC cord), and replace if necessary.

5. No lead or component should touch a high current device or a resistor rated at 1 watt or more. Lead tension around protruding metal surfaces must be avoided.

6. After reassembly of the set, always perform an AC leakage test on all exposed metallic parts of the cabinet (the channel selector knobs, antenna terminals, handle and screws) to be sure that set is safe to operate without danger of electrical shock. DO NOT USE A LINE ISOLATION TRANSFORMER DURING THIS TEST. Use an AC voltmeter having 5000 ohms per volt or more sensitivity in the following manner: Connect a 1500 ohm, 10 watt resistor, paralleled by a .15 mfd 150V AC type capacitor between a known good earth ground water pipe, conduit, etc.) and the exposed metallic parts, one at a time. Measure the AC voltage across the combination of 1500 ohm resistor and .15 mfd capacitor. Reverse the AC plug by using a non-polarized adaptor and repeat AC voltage measurements for each exposed metallic part. Voltage measured must not exceed 0.75 volts RMS. This corresponds to 0.5 milliamp AC. Any value exceeding this limit constitutes a potential shock hazard and must be corrected immediately.

PRODUCT SAFETY SERVICING GUIDELINES FOR AUDIO-VIDEO PRODUCTS

ELECTROSTATICALLY SENSITIVE DEVICES

Some semiconductor (solid-state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor “chip” components. The following techniques should be used to help reduce the incidence of component damage caused by static electricity.

1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on the body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device, which should be removed for potential shock reasons prior to applying power to the unit under test.

2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as an ESD mat, to prevent electrostatic charge buildup or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.

4. Use only an anti-static solder removal device. Some solder removal devices not classified as “anti-static” can generate electrical charges sufficient to damage ES devices.

5. Do not use freon-propelled chemicals. These can generate electrical charge sufficient to damage ES devices.

6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil, or comparable conductive material.)

7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to

the chassis or circuit assembly into which the device will stalled.

Caution: Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.

8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise, seemingly harmless motion, such as the brushing together of your clothing or the lifting of your foot from a carpeted floor, can generate static electricity sufficient to damage an ES device.)

PROGRAMMING THE REMOTE

The remote control of your HD receiver is a multibrand or universal remote control that can be programmed to operate most remote-controllable components of other manufacturers. Note that the remote control may not control all models of other brands.

To find out whether your remote control can operate the component without programming, turn on the component such as the VCR and press the corresponding mode button (VCR) on the remote control while pointing at the component. Test the POWER and CH +/- buttons to see if the component responds properly. If not, the remote requires programming to operate the device.

Turn on the component to be programmed. Then press the corresponding mode button on the remote control. Press the POWER button and the MUTE button simultaneously. Then the remote control is ready to program the code for the corresponding component. There are two ways to find the right code for the component.

A. If you press the CH +/- buttons repeatedly, the code will change one at a time. Press the POWER button after each code change. If the right code is found, the device will turn off.

B. Enter a code number using the number buttons on the remote. The right code numbers for the corresponding component can be found on the following pages. Again, if the code is correct, the device will turn off.

Press the EXIT button to store the program. Test the remote control functions to see if the component responds properly. If not, repeat from step 2.

CIRCUIT DESCRIPTIONS

POWER BLOCK

This circuit uses the FLY BACK CONVERTER for insulation. It is composed of HYBRID IC STR F6668B (which includes a POWER MOSFET) for switching power and STR G6153 as the stand-by circuit. It is operated by an ERROR AMP (IC802, SE105) which transfers a signal from the transformer secondary back to the primary.

FUNCTION & DESCRIPTION

VIN TERMINAL (PIN 4), START CIRCUIT

The Start circuit controls the operation start and stop of the control IC. In power start, C825 is charged through start resistor, R826 and R827. When the Vin terminal voltage reaches 16V (typ), the control IC starts operating. If this voltage decreases and reaches lower than 10V (typ), the control IC stops and returns initial states by the operation of UVLO (operation stop circuit).

Once started, the control circuit receives rectified power from the transformer output (Vovp = 22.5 typ).

MOSFET drain

Input control circuit power

Ground

Because the startup voltage begins to decay before the transformer can reach its set value, operation stop voltage is set at 11V (Max). This allows the control IC to keep operating until the transformer voltage can maintain it.

OCP / FB TERMINAL (PIN 1)

The Oscillator and Constant voltage control circuit uses the charge and discharge of internal condensor C1 and selects the PRC (Pulse Ratio Control) which fixes the off time of the MOSFET and varies the on time.

The Over Current Protection (OCP) circuit detects the peak value of MOSFET drain current on every pulse. This is done by connecting R821 with the MOSFET source terminal (Pin 2) and GND terminal (Pin 5) and by inputting regulated voltage to the OCP/FB terminal. The threshold voltage (Vth, 1) of the OCP terminal is about 0.73V compared with GND. External components R822 and R821 are a filter circuit to protect against a surge current generated in MOSFET on.

In light load, if the output voltage decreases, the transformer voltage in the primary also decreases proportionately. When the Vin terminal voltage in the primary drops lower than the operation stop voltage, the OCP circuit stops operating.

In this situation, the circuit current decreases so that the Vin terminal voltage increases in proportion to the charge current by start resistors R826 and R827 and intermittent operation occurs.

LATCH CIRCUIT

The latch circuit is to prevent power circuit operation by keeping the output of the oscillator low in two circuits (OVP & TSD) which protect against Over-voltage and overheating.

This circuit starts to function when OVP and TSD operate for more than 8 seconds. In this case, delay time is set by a timer circuit in the control IC.

When the Latch circuit operates, the constant voltage power (Reg) circuit in the control IC is also operating and the circuit current is high. The Vin terminal voltage decreases rapidly. If the Vin terminal voltage becomes lower than the operation stop voltage (10V typ), circuit

current drops below 400µA and the Vin terminal voltage

begins to increase. If the Vin terminal voltage reaches operation start voltage (16V typ), circuit current begins to increase and the Vin terminal voltage begins to decrease. In other words, the Vin terminal voltage rises and falls between 10V (typ) and 16V (typ). Doing this, the latch circuit protects the Vin terminal voltage from increasing abnormally.

Releasing the latch circuit is done by dropping the Vin terminal voltage below 6.5V. The latch circuit is

CIRCUIT DESCRIPTIONS

restarted after cutting AC input.

OVERHEAT PROTECTION

This circuit activates the latch circuit when the frame temperature of the Hybrid IC rises above 140°C.

The actual temperature is detected by a control circuit element. This is to protect the MOSFET from overheating.

OVER-VOLTAGE PROTECTION

This circuit activates the latch circuit when the Vin terminal voltage exceeds 22.5V (typ). This is used to protect the Vin terminal in the control circuit.

The Vin terminal is supplied by a secondary of the transformer so it is proportional to the output voltage of the transformer. Thus it is able to detect and protect the circuit against an over-voltage condition.

OPERATION STOP CIRCUIT (UVLO)

This begins operating if voltage is supplied to the low subsidiary current terminal (Vcc), Pin 5. If the supplied voltage in Vcc reaches 17.5V typ., current is supplied to circuits within the IC and then the operation stop circuit (UVLO) begins operation control and high impedence is sustained until the supplied voltage reaches the same voltage. At this time the supplied current is circuit current (Icc), in not operating, and

is 70µa (Max).

If the operation stop circuit begins operation control, circuit current (Icc) is in operation and about 15mA flows in the same terminal. In controlling operation, if the supplied voltage in this terminal goes below operation stop current voltage (Vcc), 11.5V (typ), the IC stops functioning. Like this, this terminal functions to detect supplied voltage and to control operation

start in low voltage input.

INTERNAL OSCILLATOR (OSC)

The OSC uses a capacitor (Ct) to determine oscillation frequency. When the IC begins operating, Ct is charged internally by constant current I1. This causes both SW1 and SW2 to become open. When the electric potential of the charge reaches about 4V, the comparator reverses, and SW1 and SW2 are on (closed) simultaneously.

If I1 is lower than I2, SW1 becomes on, Ct discharges and Vt decreases. Maximum Duty cycle of the oscillator is set to 80% (typ) and the frequency is set to 100KHz (typ). The globular shaped wave output is used as a timing clock in the internal circuit and the triangle shaped wave output is used as a standard signal for transforming pulse width.

CONTROL MODE (PWM LATCH / FEED BACK)

The control mode of the IC uses MIX Mode which is switched to the voltage control mode in light load and and current control mode in heavy load, linearly, according to load. The MIX control mode operates PWM control, comparing a standard triangle shaped wave with the current waveform imposed on DC FB voltage.

Input voltage difference of PWM Comparator in waveform cross becomes larger. As a result, a stable PWM signal is gained. In MIX control mode, enough noise margin can be obtained with changing the voltage PWM of standard triangle shaped wave. Also,even in continuation inductor mode in which On Duty is over 50%, Sub-harmonic phenomenon is suppressed and every essential part of internal oscillator becomes optimized.

which checks over-current on every pulse. In overcurrent, the FB system cuts the Photo Coupler for FB off because the output voltage doesn’t reach the set voltage. If an Over-current signal and an FB Current Mirror signal are detected, an internal timer starts 655ms later.

When the Count Out signal is output, the main switch is set to off and the latch circuit is activated.

When the latch circuit is activated, it needs 400µA

(Max) for maintenance. This current is influenced by the electric potential of the Vcc terminal.

If the supplied voltage in the Vcc terminal goes below power voltage for releasing latch circuit, 8.7V (typ), latch operation can be released. When the latch operation is released, this IC begins start operation from Soft Start.

2) PROTECT CIRCUIT AGAINST OVER-VOLTAGE (OVP)

D60WLCD - 923-03486 3-8 094A - SERVICING

CIRCUIT DESCRIPTIONS

If the supplied voltage in the subsidiary power terminal (Vcc) of this IC exceedes 22.2V (typ), the oscillation operation is stopped by the over-voltage protect circuit, the main switch is set to off and latch operation begins.

* power voltage Vcc (ovp) for OVP operation = 22.2V (typ)

3) PROTECT CIRCUIT AGAINST OVERHEAT (TSD) When the internal temperature of the chip reaches

150°C (typ), oscillation operation stops, the main switch is set to off and latch operation begins.

4) PROTECT CIRCUIT AGAINST OVER-CURRENT (OCP) The main switch on the drain current is monitored. If

drain current over standard value is detected, the main switch is switched to off immediately. This drain current detection is performed whenever the main switch is on. The standard voltage in the OCP terminal is 0.75V (typ).

5) SOFT START FUNCTION (SS) This IC has a Soft Start function which is timed, so an

external condensor for Soft Start is unnecessary. Soft Start is performed by increasing standard voltage for detecting over-current in a series of four steps and by controlling current in the main switch. The time and voltage level of each step is set internally.

VIDEO/SYNC SELECTOR

DESCRIPTION The CXA2151Q is a bipolar IC developed for multi scan

TVs, and incorporates a four system video switch (including HV sync signal processing) and a YCbCr output matrix circuit.

FEATURES

• Supports the I2C bus

• Supports multi scan

• Four system video switch (of which two systems support D3 pins)

• Matrix circuit

• Each YCbCr output can be switched between 0dB, 6dB (gain adjustable) and mute.

• Sync signal automatic identification circuit (with fixed mode)

• Sync separation circuit (supports HD)

• HD Tri-level sync identification circuit

• Sync signal frequency counter (both H and V)

• Dummy sync output

OPERATION

1) Programmable Matrix Selector

The CXA2151Q has a built-in four system video switch which can be selected by INPUT_SEL (I2C bus). YCbCr, HD YPbPr, GBR and the respective HV sync signals can be input to each system. Horizontal scanning line frequencies from 15 to 45kHz can be input as the range which supports multi scan.

The selected signals are output from SEL_OUT (Pins 22, 23, 25, 26 and 27), respectively. The output amplitude at this time can be selected by GAIN_SEL (I2Cbus), but when GAIN_SEL is set to 0, the gain can be adjusted by YGAIN, CBGAIN and CRGAIN (I2C bus). HV sync signal input supports both positive and negative polarity. Select MAT_OUT (I2C bus) as follows according to the input.

• Select THROUGH mode during YCbCr input.

• When YPbPr or GBR are input, select the mode that converts these signals to YCbCr.

The matrix conversion formulas are shown below.

[MAT_OUT = 1: YHDPbPr / YCbCr]: CCIR protocol

Y = YHD + 0.094Pb + 0.196Pr Cb = 0.564 (1.762Pb – 0.196Pr) Cr = 0.713 (–0.094Pb + 1.379Pr)

[MAT_OUT = 2: YHDPbPr / YCbCr]: BTA protocol

Y = YHD + 0.068Pb + 0.191Pr Cb = 0.564 (1.758Pb – 0.191Pr) Cr = 0.713 (–0.068Pb + 1.385Pr)

[MAT_OUT = 3: GBR / YCbCr]

Y = 0.3R + 0.59G + 0.11B Cb = 0.564 (–0.3R – 0.59G + 0.89B) Cr = 0.713 (0.7R – 0.59G – 0.11B)

In addition, the IN1 and IN2 systems support D3 input pins. This is selected by SELSTB_1 and SELSTB_2 (I2C bus). The control line input voltage of each L1, L2, L3 and SW pin is returned to the status register by a ternary or binary value.

Next, the HV sync signal processing block is described below. Existence distinction is first performed to determine whether the selected sync signals are input from H and V, and these results are sent as the existence status to the EV and EH status registers. On the other hand, polarity-matched H and V that passed through the polarity identification circuit are input to the priority ranking circuit.

When inputting composite sync (CS), input to the H input pin of each input system. After passing through the polarity identification circuit, V sync separation is performed and the signal is input to the priority ranking circuit.

When inputting Sync on Y or Sync on Green, input to the number 3 pin of each input system. After passing through HYSW, the signal is amplified by 6dB and output to YG_OUT (Pin 15). This output is returned to YG_IN (Pin 16) via a sync tip clamping capacitor, sync separation is performed, and the signal is input to the priority ranking circuit. This route can also be used during CS signal input by setting HYSW (I2C bus) to 1.

In addition, sync identification is performed to determine whether the input signal from YG_IN (Pin

16) is Tri-level sync, and these results are returned to the 3STATE status register. In this manner, the respective signals are input to the priority ranking circuit, and the output sync signal is determined by the EV and EH status. The priority ranking is as follows. The TV set should be designed so that one of the following three points are met.

1. When both H and V exist at the H and V pins, these signals are selected with the highest priority. $ EH = 1, EV = 1.

2. When CS exists at the H pin and there is no input at the V pin, CS is selected. EH = 1, EV = 0.

3. When Y or GREEN exists at the number 3 pin and there is no input at the H and V pins, Y or GREEN is selected. EH = 0, EV = 0.

After the HV output is determined, the H sync signal pulse width is adjusted by H_WIDTH (I2C bus), and then the H sync signal is output together with the V sync signal to SEL_OUT.

CIRCUIT DESCRIPTIONS

2) SYNC Counter

The H and V sync signals selected by the HV sync signal processing block described previously are sent to the SYNC counter block next. The SYNC counter block counts the frequency of the input H and V sync signals. The SYNC counter block counts the H sync signal input during a certain period (.5ms) based on the clock obtained by the internal VCO from the 4MHz crystal oscillator or ceramic oscillator connected to EXTCLK/ XTAL (Pin 20), and returns these results to the HNUMBERH/L status registers in 10 bits.

When the H sync signal is not input, H-NUMBER-H/L is 0 or 1. For the V sync signal, the number of reference clock (31.25kHz) pulses during 1 V cycle is counted, and these results are returned to the V-NUMBER-H/L status registers in 10 bits.

When the V sync signal is not input, the count that matches the frequency selected by VFREQ (I2C bus) is returned to VNUMBER-H/L. The SYNC count values and conversion formulas for each H and V sync signal are shown below.

Note that a 4MHz external clock can be input to EXTCLK/ XTAL (Pin 20) via a capacitor by setting CLK_SEL (I2C bus).

A dummy sync can be output by setting SELDUM (I2C bus). Select the dummy sync frequency with HFREQ and VFREQ( I2C bus). However, note that when the dummy sync is selected, the SYNC counter does not operate even if H and V sync signals are input.

3) Notes on Operation

• Processing for unused pins. OPEN: Pins 1 to 3, 7, 8, 33 to 35, 38, 39, 41 to 43, 46 and 47 Connected to GND via a capacitor and resistor: Pins 4, 5, 10, 11, 36, 37, 44 and 45 (See each H and V input and the Application Circuit). This is to prevent the SYNC counter from misoperation.

• Input the H and V inputs at sufficiently low impedance.

• Internal clamp timing. The internally generated clamp pulse follows the timings T1 and T2 shown below. Input H_IN and Sync on Y/Sync on Green so that the clamp pulse does not overlap the video interval to prevent clamping error.

SOUND PROCESSOR

INTRODUCTION The MSP 3440G family of single-chip Multistandard

Sound Processors covers the sound processing of all analog TV Standards worldwide. The full TV sound processing, starting with analog sound IF signal-in, down to processed analog AF-out, is performed on a single chip. Surround sound can be simulated with two loudspeakers. These TV sound processing ICs include versions for processing the multichannel television sound (MTS) signal conforming to the standard recommended by the Broadcast Television Systems Committee (BTSC).

The DBX noise reduction, or alternatively, MICRONAS Noise Reduction (MNR) is performed alignment free. The MSP 3440G has built-in automatic functions: The IC is able to detect the actual sound standard automatically (Automatic Standard Detection). Furthermore, pilot levels and identification signals can be evaluated internally with subsequent switching between mono/ stereo/bilingual; no I2C interaction is necessary (Automatic Sound Selection).

BTSC-Mono + SAP: Detection and FM demodulation of the aural carrier resulting in the MTS/MPX signal. Detection and evaluation of the pilot carrier, detection and FM demodulation of the SAP subcarrier. Processing of DBX noise reduction or MICRONAS Noise Reduction (MNR).

SOUND IF PROCESSING

1) Analog Sound IF Input

The input pins ANA_IN1+, ANA_IN2+, and ANA_IN-offer the possibility to connect two different sound IF (SIF) sources to the MSP 3440G. The analog-to-digital conversion of the preselected sound IF signal is done by an A/D converter. An analog automatic gain circuit (AGC) allows a wide range of input levels. The highpass filters are formed by the coupling capacitors at pins ANA_IN1+ and ANA_IN2+.

2) Demodulator: Standards and Features

The MSP 3440G is able to demodulate all TV-sound standards worldwide including the digital NICAM system.

Very high deviation FM-Mono: Detection and robust demodulation of one FM carrier with a maximum deviation of 540 kHz.

BTSC-Stereo: Detection and FM demodulation of the aural carrier resulting in the MTS/MPX signal. Detection and evaluation of the pilot carrier, AM demodulation of the (L-R)-carrier and detection of the SAP subcarrier. Processing of DBX noise reduction or MICRONAS Noise Reduction (MNR).

Since for RGB type inputs, the blanking level will correspond to a low output code of the A/D, it makes sense to center the clamp range around a (0) A/D output code. In this way the user can either offset up or down this level symmetrically around (0). If the clamping is set such that the blanking level corresponds to a level below (0), the A/D output is clipped at code 0.

2) Clamping Circuit

The purpose of clamping is to provide the input signal with a known DC-value. Typically video signals will be AC-coupled into the part. The signal needs to be levelshifted to fall between the reference voltage range(VREFB..VREFT) of the A/D. By supplying a programmable clamp, the user can shift the input signal with respect to the A/D range. This has the same effect as keeping the input signal constant and applying offset to both A/D reference voltages while keeping the VREFT-VREFB difference equal. However no external adjustments are needed with this implementation.

For video, the clamping circuit can only be active during the non-active video portion of each line to avoid changes in brightness along the line. Clamping is done during the horizontal blanking interval, either on the backporch of sync or during the sync tip (in the case of a sync present on at least one of the video channels).

If HS is carried on a separate line, as is typically the case for PC graphics, clamping is done during blanking.

CIRCUIT DESCRIPTIONS

In the case of YUV input signals, blanking levels for U & V correspond to the midlevel analog input. To handle these signals the clamping range should be centered on the midlevel output code of the A/D.

The clamp code is 8 bits wide and spans 128 ADC output codes (a 2 LSB change to clamp code corresponds nominally to 1 LSB change in ADC output code). The programmed clamp code is independent of the PGA setting (see later). This ensures independent brightness/clamping control.

The clamp pulse defines the timing window during which the clamp circuit is internally enabled, and is either generated externally and supplied to the device, or it can be internally generated. In the latter case the user can program both the position and width of the clamp pulse with respect to the horizontal sync (HS) input.

3) Programmable Gain Amplifier (PGA)

Each video channel is passed through a programmable gain amplifier, to provide a full-scale signal to each A/ D. The user can change this gain via register programming. Any gain change becomes effective immediately. The range of the PGA is such that an input ac range from 0.4Vpp to 1.2Vpp can be scaled to ADC full scale, by maximum gain and minimum gain settings respectively.

The PGA is split into a 6 bit coarse gain control and 5 bit fine gain control. Their combination leads to a PGA resolution of better than 1 LSB on the ADC output code. The bandwidth of the PGA is constant, resulting in a constant analog video input bandwidth. The coarse PGA, with its 64 settings, covers a 4/3x to 4x gain change, used for a 0.4V (0.4Vpp x 4 = 1.6Vpp) resp.

1.2Vpp (1.2Vpp x 4/3 = 1.6Vpp) input range swing.

While an amplifier with variable gain implements the coarse PGA, the fine PGA is implemented by slightly changing the top & bottom reference levels that are also independently controllable for each ADC channel.

The fine range, with its 32 settings, covers a range of 16 LSB’s. The fine and coarse PGA settings can be combined into a single PGA gain formula as follows: GAIN = (4/3 + C/24)(1 +(F-15)/512)

Where C is the coarse gain setting (0..63) and F the fine gain setting (0..31).

4) A/D Converter

The A/D converter is based on the core used in the TLV5580 (single 8-bit 80 MSPS A/D). The switchedcapacitor single- pipeline CMOS architecture combines excellent signal-to-noise characteristics with a very wide 3dB analog input bandwidth of typ. 500 MHz. The A/ D block contains an internal reference voltage generator, providing stable bottom and top references derived from an internal bandgap reference. The reference voltages are made available externally. THS8083

supports both A/C and D/C coupled input (clamping disabled). In the latter case, the externally made available references can be used to level-shift the input signal.

The A/D converter is guaranteed up to 80 MSPS (THS8083) or 95 MSPS (THS8083-95) with no missing codes. The sampling clock of the A/D converter is either fed from external or generated internally by the PLL.

5) Output formatter

This block enables either a 4:4:4 24-bit output or 4:4:4 48-bit output at half the pixel clock or a 4:2:2 16-bit output, useful for YUV digitizing (ITU.BT-601 style). In the latter case 8-bit is used for the Y output, while a 2nd 8 bit port is used alternately for Cr and Cb. As per ITU BT-601, Cb is the first video data word for each line, as shown in Figure.

The first color sample after an incoming HS will be Cb.. The output signal DHS is synchronized to the first pixel of a line and can therefore be used to uniquely identify Cb from Cr output data in downsampled modes.
