Setting up a DDR5 receiver compliance test

Ensuring compliance of the fifth generation of double data rate memory (DDR5) devices requires performance of an exhaustive list of interoperability tests set forth the JEDEC specifications. Physical layer receiver conformance testing involves characterization of the receiver, calibration of a stress signal using a high-bandwidth oscilloscope, and device receiver tests using a bit error ratio tester.

Calibrating the test setup requires precise instruments and is prone to user error, especially without expertise in the nuances of the latest DDR5 compliance test specifications. Manually performing each bit error ratio measurement on the DDR5 DRAM or other device with the calibrated stress signal, recording the results, and comparing them with the test specification is time-consuming. Automated DDR5 receiver test compliance software is required.

DDR5 receiver compliance test solution

DDR5 receiver testing for JEDEC specifications requires precise test tools. The Keysight DDR5 receiver compliance test solution includes the M80885RCA receiver test automation software running on the M8040A bit error ratio tester which aids in setup, test execution, results evaluation, and compliance documentation to ensure conformance to the DDR5 specifications. The Keysight UXR-Series oscilloscope, with D9120ASIA signal integrity software and D9120JITA jitter analysis software, is used to characterize the receiver.
