4. MULTI STANDARD SOUND PROCESSOR

5. VIDEO SWITCH TEA6415

In case of three or more external sources are used, the video switch IC TEA6415 is used. The main function of this device is to switch 8 video-input sources on the 6 outputs. Each output can be switched on only one of each input. On each input an alignment of the lowest level of the signal is made (bottom of sync. top for CVBS or black level for RGB signals). Each nominal gain between any input and output is 6.5dB.For D2MAC or Chroma signal the alignment is switched off by forcing, with an external resistor bridge, 5VDC on the input. Each input can be used as a normal input or as a MAC or Chroma input (with external Resistor Bridge). All the switching possibilities are changed through the BUS. Driving 75ohm load needs an external resistor. It is possible to have the same input connected to several outputs.

12.2. LM2576

12.2.1. General Description

The LM2576 series of regulators are monolithic integrated circuits ideally suited for easy and convenient design of a step–down switching regulator (buck converter). All circuits of this series are capable of driving a 3.0 A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5.0 V, 12 V, 15 V, and an adjustable output version. These regulators were designed to minimize the number of external components to simplify the power supply design. Standard series of inductors optimized for use with the LM2576 are offered by several different inductor manufacturers. Since the LM2576 converter is a switch–mode power supply, its efficiency is significantly higher in comparison with popular three–terminal linear regulators, especially with higher input voltages. In many cases, the power dissipated is so low that no heatsink is required or its size could be reduced dramatically. A standard series of inductors optimized for use with the LM2576 are available from several different manufacturers. This feature greatly simplifies the design of switch–mode power supplies. The LM2576 features include a guaranteed ±4% tolerance on output voltage within specified input voltages and output load conditions, and ±10% on the oscillator frequency (±2% over 0°C to 125°C). External shutdown is included, featuring 80 mA (typical) standby current. The output switch includes cycle–by–cycle current limiting, as well as thermal shutdown for full protection under fault conditions.

12.6. TEA6415

12.6.1. General description

The main function of the IC is to switch 8 video input sources on 6 outputs. Each output can be switched on only one of each input. On each input an alignment of the lowest level of the signal is made (bottom of synch. top for CVBS or black level for RGB signals). Each nominal gain between any input and output is

6.5dB. For D2MAC or Chroma signal the alignment is switched off by forcing, with an external resistor bridge, 5 V

DC on the input. Each input can be used as a normal input or as a MAC or Chroma input (with

external resistor bridge). All the switching possibilities are changed through the BUS. Driving 75 load needs an external transistor.

Horizontal Sync Output A reconstructed and phase-aligned version of the Hsync input. Both the polarity and duration of this output can be programmed via serial bus registers. By maintaining alignment with DATACK and Data, data timing with respect to horizontal sync can always be determined.

Vertical Sync Output A reconstructed and phase-aligned version of the video Vsync. The polarity of this output can be controlled via a serial bus bit. The placement and duration in all modes is set by the graphics transmitter.

Sync-On-Green Slicer Output This pin outputs either the signal from the Sync-on-Green slicer comparator or an unprocessed but delayed version of the Hsync input. (Note: Besides slicing off SOG, the output from this pin gets no other additional processing on the AD9883A. Vsync separation is performed via the sync separator.)

Data Output, RED Channel Data Output, GREEN Channel Data Output, BLUE Channel The main data outputs. Bit 7 is the MSB. The delay from pixel sampling time to output is fixed. When the sampling time is changed by adjusting the PHASE register, the output timing is shifted as well. The DATACK and HSOUT outputs are also moved, so the timing relationship among the signals is maintained.

Data Output Clock

This is the main clock output signal used to strobe the output data and HSOUT into external logic. It is produced by the internal clock generator and is synchronous with the internal pixel sampling clock. When the sampling time is changed by adjusting the PHASE register, the output timing is shifted as well. The Data, DATACK, and HSOUT outputs are all

moved, so the timing relationship among the signals is maintained.

Analog Input for RED Channel Analog Input for GREEN Channel Analog Input for BLUE Channel High impedance inputs that accept the RED, GREEN, and BLUE channel graphics signals, respectively. (The three channels are identical, and can be used for any colors, but colors are assigned for convenient reference.) They accommodate input signals ranging from 0.5 V to 1.0 V full scale. Signals should be ac-coupled to these pins to support clamp operation.

Horizontal Sync Input This input receives a logic signal that establishes the horizontal timing reference and provides the frequency reference for pixel clock generation. The logic sense of this pin is controlled by serial register 0Eh Bit 6 (Hsync Polarity). Only the leading edge of Hsync is active; the trailing edge is ignored. When Hsync Polarity = 0, the falling edge of Hsync is used. When Hsync Polarity = 1, the rising edge is active. The input includes a Schmitt trigger for noise immunity, with a nominal input threshold of 1.5 V.

Vertical Sync Input This is the input for vertical sync.

Sync-on-Green Input This input is provided to assist with processing signals with embedded sync, typically on the GREEN channel. The pin is connected to a high speed comparator with an internally generated threshold. The threshold level can be programmed in 10 mV steps to any voltage between 10 mV and 330 mV above the negative peak of the input signal. The default voltage threshold is 150 mV. When connected to an ac-coupled graphics signal with embedded sync, it will produce a noninverting digital output on SOGOUT. (This is usually a composite sync signal, containing both vertical and horizontal sync information that must be separated before passing the horizontal sync signal to Hsync.) When not used, this input should be left unconnected. For more details on this function and how it should be configured, refer to the Sync-on-Green section.

External Clamp Input This logic input may be used to define the time during which the input signal is clamped to ground. It should be exercised when the reference dc level is known to be present on the analog input channels, typically during the back porch of the graphics signal. The CLAMP pin is enabled by setting control bit Clamp Function to 1, (register 0FH, Bit 7, default is 0). When disabled, this pin is ignored and the clamp timing is determined internally by counting a delay and duration from the trailing edge of the Hsync input. The logic sense of this pin is controlled by Clamp Polarity register 0FH, Bit 6. When not used, this pin must be grounded and Clamp Function programmed to 0.

Clock Generator Coast Input (Optional) This input may be used to cause the pixel clock generator to stop synchronizing with Hsync and continue producing a clock at its current frequency and phase. This is useful when processing signals from sources that fail to produce horizontal sync

pulses during the vertical interval. The COAST signal is generally not required for

PC-generated signals. The logic sense of this pin is controlled by Coast Polarity (register 0FH, Bit 3). When not used, this pin may be grounded and Coast Polarity programmed to 1, or tied HIGH (to VD through a 10 k resistor) and Coast Polarity programmed to 0. Coast Polarity defaults to 1 at power-up.

Internal Reference BYPASS Bypass for the internal 1.25 V band gap reference. It should be connected to ground through a 0.1 µF capacitor. The absolute accuracy of this reference is ±4%, and the temperature coefficient is ±50 ppm, which is adequate for most AD9883A applications. If higher accuracy is required, an external reference may be employed instead.

Midscale Voltage Reference BYPASS Bypass for the internal midscale voltage reference. It should be connected to ground through a 0.1 µF capacitor. The exact voltage varies with the gain setting of the BLUE channel.

External Filter Connection For proper operation, the pixel clock generator PLL requires an external filter. Connect the filter shown in Figure 6 to this pin. For optimal performance, minimize noise and parasitics on this node.

Main Power Supply These pins supply power to the main elements of the circuit. They should be as quiet and filtered as possible.

Digital Output Power Supply A large number of output pins (up to 25) switching at high speed (up to 110 MHz) generate a lot of power supply transients (noise). These supply pins are identified separately from the VD pins so special care can be taken to minimize output noise transferred into the sensitive analog circuitry. If the AD9883A is interfacing with lower voltage logic, VDD may be connected to a lower supply voltage (as low as

2.5 V) for compatibility.

Clock Generator Power Supply The most sensitive portion of the AD9883A is the clock generation circuitry. These pins provide power to the clock PLL and help the user design for optimal performance. The designer should provide “quiet,” noise-free power to these pins.

Ground The ground return for all circuitry on chip. It is recommended that the AD9883A be assembled on a single solid ground plane, with careful attention to ground current paths.

This is the Pixel clock input for chip. The MC141585 chip is driven by this pixel clock for all the logics inside.

Page 26

NC (Pin 3)

No connection.

(Pin 4)

This is the +5V power pin for the chip.

HSYNC (Pin 5)

This pin inputs a horizontal synchronize signal. It is negative polarity by default. The leading edge of HSYNC synchronizes its internal horizontal timing. The maximum input ratio between PIXin/HSYNC should not greater than 1580 for displaying 12X18 font matrix. For displaying 10X18 font matrix, this ratio should not greater than 1280.

RESET (Pin 6)

An active low signal will reset ROW15 and ROW16 control registers. Refer to Control Registers section for default set-tings. A proper RC network have to be tighten to this pin to ensure the device initialize properly during power up. Refer to the application diagram.

SDA (Pin 7)

Data and control message are being transmitted to this chip from a host MCU via M_bus systems. This wire is configurated as a uni-directional data line. (Detailed description of protocols will be discussed in the M_BUS section).

SCL (Pin 8)

A separate synchronizing clock input from the transmitter is required for M_Bus protocol. Data is read at the rising edge of each clock signal.

(Pin 9)

This is the power pin for the digital logic of the chip.

VSYNC (Pin 10)

Similar to Pin 5, this pin inputs a vertical synchronize signal to synchronize the vertical control circuit. It is negative polarity by default.

(I) (Pin 11)

This is the voltage supply of RGB outputs when low intensity of Windows/ROW is selected. The RBG output level would be equal to VDD(I) in this case. Please refer to Row Attribute/Window registers for more detail. The input voltage for this pin should be equal to or less than V DD (Pin 17) for normal operation.

FBKG (Pin 12)

This pin will output a logic high while displaying characters or windows. It is defaulted to high impedance state after power on, or when there is no output. An external 10 κΩ resistor pulled low is recommended to avoid level toggling caused by hand effect when there is no output.

12.17. MSP34X0G (MSP3410G)

Multistandard Sound Processor Family

12.17.1. Introduction

The MSP 34x0G family of single-chip Multistandard Sound Processors covers the sound processing of all analog TV-Standards worldwide, as well as the NICAM digital sound standards. The full TV sound processing, starting with analog sound IF signal-in, down to processed analog AF-out, is performed on a single chip. Figure shows a simplified functional block diagram of the MSP 34x0G. This new generation of TV sound processing ICs now includes 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. Other processed standards are the Japanese FM-FM multiplex standard (EIA-J) and the FM Stereo Radio standard. Current ICs have to perform adjustment procedures in order to achieve good stereo separation for BTSC and EIA-J. The MSP 34x0G has optimum stereo performance without any adjustments. All MSP 34x0G versions are pin and software downward compatible to the MSP 34x0D. The MSP 34x0G further simplifies controlling software. Standard selection requires a single I²C transmission only. The MSP 34x0G 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).

Source Select

S bus interface consists of five pins:

1. I2S_DA_IN1, I2S_DA_IN2: For input, four channels (two channels per line, 2*16 bits) per sampling cycle (32 kHz) are transmitted.

2. I2S_DA_OUT: For output, two channels (2*16 bits) per sampling cycle (32 kHz) are transmitted.

3. I2S_CL: Gives the timing for the transmission of I

S serial data (1.024 MHz).

4. I2S_WS: The I2S_WS word strobe line defines the left and right sample.

12.18. DS90C385

12.18.1. General Description

The DS90C385 transmitter converts 28 bits of LVCMOS/LVTTL data into four LVDS (Low Voltage Differential Signaling) data streams. A phase-locked transmit clock is transmitted in parallel with the data streams over a fifth LVDS link. Every cycle of the transmit clock 28 bits of input data are sampled and transmitted. At a transmit clock frequency of 85 MHz, 24 bits of RGB data and 3 bits of LCD timing and control data (FPLINE, FPFRAME, DRDY) are transmitted at a rate of 595 Mbps per LVDS data channel. Using a 85 MHz clock, the data throughput is 297.5 Mbytes/sec. Also available is the DS90C365 that converts 21 bits of LVCMOS/LVTTL data into three LVDS (Low Voltage Differential Signaling) data streams.
