P ADC analog ground.
4.4. M29W800AT
Low Voltage Single Supply Flash Memory to store PW1306 code.
ELECTRONIC SIGNATURE
– Manufacturer Code: 20h
– Top Device Code, M29W800AT: D7h
4.5. DS90C385
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.

20 to 85 MHz shift clock support

Tx power consumption <130 mW (typ) @85MHz Grayscale

Supports VGA, SVGA, XGA and Dual Pixel SXGA.

Up to 2.38 Gbps throughput

Up to 297.5 Megabytes/sec bandwidth

PLL requires no external components

Compatible with TIA/EIA-644 LVDS standard
4.6. P15V330
The PI5V330 is a true bidirectional Quad 2-channel multiplexer/demultiplexer that is for both RGB and composite video
switching applications.

200 MHz bandwidth

3 Ohm on-resistance

Switching at 10 ns

100 mA output current
4.7. 74HC4052
The 74HC/HCT4052 are dual 4 -channel analog multiplexers/demultiplexers with common select logic. Each multiplexer has
four independent inputs/outputs (nY0 to nY3) and a common input/output (nZ). The common channel select logics include two
digital select inputs (S0 and S1) and an active LOW enable input (E).

Wide analog input voltage range: ± 5 V.

Low “ON” resistance:
