Introduction
National Semiconductor’s Interface Products Group Channel Link demo kit contains a
Transmitter (Tx) demo board and a Receiver (Rx) demo board along with an interface
cable.
Voltage Differential Signaling (LVDS) through a cable at seven times the input clock
rate.
The Transmitter board accepts 3V TTL/CMOS data signals from an incoming data
source along with the clock signal. The LVDS Transmitter converts the TTL/CMOS
parallel lines into serialized LVDS pairs. The serial data streams toggle at 7 times the
clock speed.
The Receiver board accepts the LVDS serialized data (and clock) and converts them
back into parallel 3V TTL/CMOS data out signals.
The user needs to provide the proper data inputs to the Transmitter and also to provide
a proper interface from the Receiver output to the receiver devices. A cable harness
scramble may be necessary depending on type of cable/connector interface used.
Warnings:
The maximum voltage that should ever be applied to the Channel Link Transmitter or
Receiver Vcc is 4V. The Transmitter and Receiver power supply pins (Vccs) are NOT
5V tolerant. The Transmitter can however accept a 3.3V or 5V TTL/CMOS level on the
inputs (TxIN). The Transmitter inputs are 5V tolerant. The maximum voltage that can
be applied to any input pin is 5.0V.
This kit will demonstrate the chipsets transmitting data streams using Low
