11.2. LM2576
11.2.1. 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.

11.8. TEA6415
11.8.1. 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. It is possible to have the same input connected to several outputs. The
starting configuration upon power on (power supply: 0 to 10V) is undetermined. In this case, 6 words of 16
bits are necessary to determine one configuration. In other case, 1 word of 16 bits is necessary to
determine one configuration.

11.17. AD9883A
11.17.1. General description
The AD9883A is a complete 8-bit, 140 MSPS monolithic analog interface optimized for capturing RGB
graphics signals from personal computers and workstations. Its 140 MSPS encode rate capability and full
power analog bandwidth of 300 MHz supports resolutions up to SXGA (1280 1024 at 75 Hz).
The AD9883A includes a 140 MHz triple ADC with internal 1.25 V reference, a PLL, and programmable
gain, offset, and clamp control. The user provides only a 3.3 V power supply, analog input, and Hsync and
COAST signals. Three-state CMOS outputs may be powered from 2.5 V to 3.3 V.
The AD9883A’s on-chip PLL generates a pixel clock from the Hsync input. Pixel clock output frequencies
range from 12 MHz to 140 MHz. PLL clock jitter is 500 ps p-p typical at 140 MSPS. When the COAST
signal is presented, the PLL maintains its output frequency in the absence of Hsync. A sampling phase
adjustment is provided. Data, Hsync, and clock output phase relationships are maintained. The AD9883A
also offers full sync processing for composite sync and sync-on-green applications.
A clamp signal is generated internally or may be provided by the user through the CLAMP input pin. This
interface is fully programmable via a 2-wire serial interface.
Fabricated in an advanced CMOS process, the AD9883A is provided in a space-saving 80-lead LQFP

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.)

DATACK
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.

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).

(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).

11.21. DS90C385
11.21.1. 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. Both transmitters can be programmed for Rising edge strobe or Falling edge strobe through a
dedicated pin. A Rising edge or Falling edge strobe transmitter will interoperate with a Falling edge strobe
Receiver (DS90CF386/DS90CF366) without any translation logic.
The DS90C385 is also offered in a 64 ball, 0.8mm fine pitch ball grid array (FBGA) package which
provides a 44 % reduction in PCB footprint compared to the TSSOP package. This chipset is an ideal

12.7.1. General Description
The MX29LV160T/B & MX29LV160AT/AB is a 16-megabit Flash memory organized as 2M bytes of 8 bits
or 1M words of 16 bits. MXIC's Flash memories offer the most cost-effective and reliable read/write nonvolatile random access memory. The MX29LV160T/B & MX29LV160AT/AB is packaged in 44-pin SOP,
48-pin TSOP and 48-ball CSP. It is designed to be reprogrammed and erased in system or in standard
EPROM programmers.
The standard MX29LV160T/B & MX29LV160AT/AB offers access time as fast as 70ns, allowing operation
of high-speed microprocessors without wait states. To eliminate bus contention, the MX29LV160T/B
&MX29LV160AT/AB has separate chip enable (CE) and output enable (OE) controls.
MXIC's Flash memories augment EPROM functionality with in-circuit electrical erasure and programming.
The MX29LV160T/B & MX29LV160AT/AB uses a command register to manage this functionality. The
command register allows for 100% TTL level control inputs and fixed power supply levels during erase and
programming, while maintaining maximum EPROM compatibility.
MXIC Flash technology reliably stores memory contents even after 100,000 erase and program cycles.
The MXIC cell is designed to optimize the erase and programming mechanisms. In addition, the
combination of advanced tunnel oxide processing and low internal electric fields for erase and program
operations produces reliable cycling. The MX29LV160T/B & MX29LV160AT/AB uses a 2.7V~3.6V VCC
supply to perform the High Reliability Erase and auto Program/Erase algorithms.
The highest degree of latch-up protection is achieved with MXIC's proprietary non-epi process. Latch-up
protection is proved for stresses up to 100 milliamps on address and data pin from -1V to VCC + 1V.

SERIAL CLOCK (SCL): The SCL input is used to positive edge clock data into each EEPROM device and
negative edge clock data out of each device.
SERIAL DATA (SDA): The SDA pin is bidirectional for serial data transfer. This pin is open-drain driven
and may be wire-ORed with any number of other open-drain or open collector devices.
DEVICE/PAGE ADDRESSES (A2, A1, A0): The A2, A1 and A0 pins are device address inputs that are
hard wired or left not connected for hardware compatibility with AT24C16. When the pins are hardwired, as
many as eight 32K/64K devices may be addressed on a single bus system (device addressing is
discussed in detail under the Device Addressing section). When the pins are not hardwired, the default A
A

12.9. STV0360
12.9.1. General Description
The STV0360 is a single-chip COFDM (coded orthogonal frequency division multiplex) demodulator that
performs IF to MPEG-2 block processing of OFDM carriers. It is intended for digital terrestrial receivers for
compressed video, sound and data services.
The chip implements all the functions from the tuner IF output up to the MPEG-2 transport stream input.
The STV0360 is fully compliant with the DVB-T specification (ETS 300 744) and handles 2K/8K modes.
The STV0360 integrates an A/D converter that delivers the required performance to handle up to 64 QAM
carriers in a direct IF sampling architecture, thus eliminating the need for an external down-converter. The
chip also integrates an internal programmable gain amplifier (PGA) to compensate for SAW filter level
degradation, thus eliminating the need for external IF amplifiers. A 10-bit ADC, intended for RF signal
strength indication, eliminates the need for external components when using wide-band AGC tuners.
In addition to all the demodulation and FEC (forward error correction) functions required for recovery of the
QAM modulated bit streams with very low BER, it also includes several features that give easy and
immediate access to various quality monitoring parameters or lock status. The STV0360 also provides
output such as delayed AGC or noise-free I²C bus dedicated to tuner control, which facilitates the design of
high quality integrated receiver decoders.
The STV0360 outputs error-corrected MPEG-2 transport streams and complies with the DVB common
interface format, with programmable data clock frequency. It also interfaces seamlessly with the packet demultiplexers embedded in the STi55xx Omega family of single-chip decoders.
