Abstract:
The present invention implements a method and apparatus for using components within a Serializer/DeSerializer (SerDes) to emulate the effects of a backplane in order to facilitate automated test equipment (ATE) testing of the SerDes. The SerDes includes a transmitter pre-emphasis circuit (TPXE) that pre-emphasizes a transmitted signal and a receiver equalization circuit (RXEQ) that equalizes a received signal. The TPXE includes coefficients that are dynamically programmable.
