DESCRIPTION
The SN65LVDS308 receiver deserializes FlatLink
3G-compliant serial input data to 27 parallel data
outputs. The SN65LVDS308 receiver contains one
shift register to load 30 bits from two serial inputs
and latches the 24 pixel bits and 3 control bits out to
the parallel CMOS outputs after checking the parity
bit. If a parity error is detected, the data output bus
disregards the newly received pixel. Instead, the last
data word is held on the output bus for another clock
cycle.
The serial data and clock are received via
sub-low-voltage differential signalling (SubLVDS)
lines. The SN65LVDS308 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 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 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.
