Abstract
Methods and apparatus provide a transceiver, such as a serializer/deserializer device (SerDes), with enhanced built-in self test (BIST). A built-in self test circuit is provided that decouples a clock signal used for receiving data from a clock signal used in transmitting data. This permits data tracking circuitry of a receiver to be efficiently tested with a relatively simple loop back test.
