Abstract :
In this paper we will describe a solution to test I/O cells that use four level pulse amplitude modulation (PAM-4) at data rates of 32 Gbaud using a commercial ATE platform without any external instruments. The solution is based on an active test fixture where a retimed digital to analog converter (DAC) is used to generate the PAM-4 stimulus signaling. The comparator side is implemented using a single differential comparator and three consecutive functional tests with different patterns and compare threshold voltages.
