SLLS765B–SEPTEMBER 2006–REVISED FEBRUARY 2007
PROGRAMMABLE 27-BIT SERIAL-TO-PARALLEL RECEIVER
The serial data and clock are received via
sub-low-voltage differential signalling (SubLVDS)
lines. The SN65LVDS306 supports three operating
power modes (shutdown, standby, and active) to
conserve power.
FEATURES

Data and 3 Control Bits Received Over One
SubLVDS Differential Line
When receiving, the PLL locks to the incoming clock
CLK and generates an internal high-speed clock at
the line rate of the data line. The data is serially
loaded into
a shift register using the internal

high-speed clock. The deserialized data is presented
on the parallel output bus with a recreation of the
pixel clock, PCLK, generated from the internal
high-speed clock. If no input CLK signal is present,
the output bus is held static with 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.

DESCRIPTION
The
SN65LVDS306
receiver
deserializes
LVDS306
CLK DATA
LVDS305
FlatLink™3G-compliant serial input data to 27
parallel data outputs. The SN65LVDS306 receiver
contains one shift register to load 30 bits from one
serial input 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.
