An illustrative spread spectrum clocking (SSC) converter includes: a deserializer to receive a data stream with an unmodulated clock; a memory coupled to the deserializer to buffer the data stream; and a serializer coupled to the memory to retransmit the data stream with a spread spectrum clock. One illustrative conversion method, which may be implemented on a monolithic integrated circuit device, includes: receiving a data stream from an external transmitter in an unmodulated clock domain; storing the data stream in a buffer; and retransmitting the data stream with a spread spectrum clock. Such converters and methods may be employed in an illustrative system having: a test module to generate test data streams and to analyze result data streams for verifying operation of one or more devices under test in a spread spectrum clock domain as the test module operates in an unmodulated clock domain.
