DESCRIPTION
The
SN65LVDS302
FlatLink3G compliant serial input data to 27
parallel data outputs. The SN65LVDS302 receiver
contains one shift register to load 30 bits from 1, 2 or
3 serial inputs and latches the 24 pixel bits and 3
control bits out to the parallel CMOS outputs after
checking the parity bit. If the parity check confirms
correct parity, the Channel Parity Error (CPE) output
remains low. If a parity error is detected, the CPE
output generates a high pulse while the data output
bus disregards the newly-received pixel. Instead, the
last data word is held on the output bus for another
clock cycle.

PROGRAMMABLE 27-BIT SERIAL-TO-PARALLEL RECEIVER
The serial data and clock are received via Sub
Low-Voltage Differential Signalling (SubLVDS) lines.
The SN65LVDS302 supports three operating power
modes (Shutdown, Standby, and Active) to conserve
power.
When receiving, the PLL locks to the incoming clock
CLK and generates an internal high-speed clock at
the line rate of the data lines. The data is serially
loaded
into
a

register
high-speed clock. The deserialized data is presented
on the parallel output bus with a recreation of the

generated
high-speed clock. If no input CLK signal is present,
the output bus is held static with the PCLK and DE
held low, while all other parallel outputs are pulled
high.

The parallel (CMOS) output bus offers a bus-swap
feature. The SWAP control pin controls the output
pin order of the output pixel data to be either R[7:0].
G[7:0], B[7:0], VS, HS, DE or B[0:7], G[0:7], R[0:7],
VS, HS, DE. This gives a PCB designer the flexibility
to better match the bus to the LCD driver pinout or to
put the receiver device on the top side or the bottom
side of the PCB. The F/S control input selects
between a slow CMOS bus output rise time for best
EMI and power consumption and a fast CMOS
output for increased speed or higher load designs.
