• Manufacturer Part Number: DS90CR218
• Description: +3.3V Rising Edge Data Strobe LVDS 21-Bit Channel Link Receiver - 75 MHz
• Manufacturer: National Semiconductor

Applications Information
The CHANNEL LINK chipset is designed to protect itself
from accidental loss of power to either the transmitter or
receiver. If power to the transmit board is lost, the receiver
clocks (input and output) stop. The data outputs (RxOUT)

retain the states they were in when the clocks stopped.
When the receiver board loses power, the receiver inputs are
shorted to V
(5 mA per input) by the fixed current mode drivers, thus
avoiding the potential for latchup when powering the device.
