Mstar MST5251A scaler
The MST5251A is a high performance and fully integrated
graphics processing IC solution for multi-function LCD monitor/
TV with resolutions up to UXGA/WUXGA. It is configured with
an integrated triple-ADC/PLL, an integrated DVI/HDCP/HDMI
receiver, two video de-interlacers, two high quality scaling
engines, an on-screen display controller, and a built-in output
clock generator. By use of external frame buffer, PIP/POP is
provided for multimedia applications. It supports de-interlaced
full-screen video, video-on-graphic overlay, split screen, frame
rate conversion, and aspect ratio conversion for various video
sources. To further reduce system costs, the MST5251A also
integrates intelligent power management, control capability for
green-mode requirements and spreadspectrum support for
EMI management.

NEC uPD64015 Video Decoder
The uPD64015 is a video decoder LSI with an on-chip
threedimensional Y/C separation function that supports
NTSC-M and PAL-BDGHI composite signals and a
threedimensional noise reduction function that supports all
input signals. It includes four high-accuracy A/D converter
channels for analog video input, an anti-alias filter, Y/C
separation, chroma decoding supporting NTSC/PAL/SECAM,
threedimensional noise reduction supporting all input signals,
and various definition correction functions, and supports digital
colour difference output. The uPD64015 incorporates a 3-
channel DAC and can output decoded video signals or signals
output from the incorporated SG (Signal Generator), in the form
of RGB or analog colour difference signals.
9.3
TI PCM1753 Audio DAC
The PCM1753/54/55 is a CMOS, monolithic, integrated circuit,
which includes stereo digital-to-analog converters and support
circuitry in a small 16-lead SSOP package. The data
converters use TI's enhanced multi level delta-sigma
architecture, which employs 4
amplitude quantization to achieve excellent dynamic
performance and improved tolerance to clock jitter. The
PCM1753/54/55 accepts industry standard audio data formats
with 16- to 24-bit data, providing easy interfacing to audio DSP
and decoder chips. Sampling rates up to 200 kHz are
supported. A full set of user programmable functions is
accessible through a three wire serial control port, which
supports register write functions.

JRC NJW1141 Audio Processor
The NJW1141 is a sound processor includes all of the
functions required to process the audio signal for TV, such as
tone control, balance, volume, mute, and AGC functions. All of
the internal status and variables are controlled by I
interface.
9.5
Winbond W79E659 MCU
The W79E659 is a fast, 8051/52-compatible microcontroller
with a redesigned processor core that eliminates wasted clock
and memory cycles. Typically, the W79E659 executes
instructions 1.5 to 3 times faster than that of the traditional
8051/52, depending on the type of instruction, and the overall
performance is about 2.5 times better at the same crystal
speed. As a result, with the fully-static CMOS design, the
W79E659 can accomplish the same throughput with a lower
clock speed, reducing power consumption. The W79E659
provides 256 bytes of on-chip RAM; 1-KB of auxiliary RAM;
seven 8-bit, bi-directional and bit-addressable I/O ports; an
additional 4-bit port P4; three 16-bit timer/counters; an UART
serial port, 2 channels of I
8 channels of 10-bit ADC. These peripherals are all supported
by ten interrupt sources with 2 levels of priority. The W79E659
contains a 32-KB Flash EPROM whose contents may be
updated in-system by a loader program stored in an auxiliary,
4-KB Flash EPROM. Once the contents are confirmed, it can
be protected for security.
9.6
Fintek F75101R GPIO Expander
The F75101R is a multi functional general purpose I/O chip
providing 16 GPIO powered by 3VSB by power on setting.
Level or pulse modes can be programmed by registers. With
2 sets of watchdog timer, F75101R provides more flexible
control for system.
9.7
Eon EN29F040A 4MBit Flash
The EN29F040A is a 4-Megabit, electrically erasable, read/
write non-volatile flash memory organized into 512K words with
8 bits per word, the 4M of memory is arranged in eight uniform
sectors of 64 Kilobytes each. Any byte can be programmed
typically in 10 μs. The EN29F040A features 5.0 V voltage read
and write operation, with access times as fast as 45 ns to
eliminate the need for WAIT states in high-performance
microprocessor systems.
9.8
YAMAHA YDA138 Audio Amplifier
The YDA138 (D-3) is a high efficient digital audio power
amplifier IC that operates with a single 12 V power supply. An
audio power amplifier with a maximum output of 10 W (R
8 Ω) 2 channels can be configured with one chip. YDA138 has
a "Pure Pulse Direct Speaker Drive Circuit" which directly
drives speakers while reducing distortion of pulse output signal
and reducing noise on the signal, and realizes the highest
standard low distortion rate characteristics and low noise
characteristics as 10 W-class of output digital amplifier IC. In
addition, circuit design with fewer external parts can be made
depend on the condition of use because corresponds to filter
less. YDA138 provides overcurrent protection function for
speaker output terminals, IC thermal protection function, POP
noise reduction function, and AM interference measures
function as well as power-down and output mute functions.
