Physical-layer (PHY) electrical tests for DDR5 transmitter compliance involve executing a wide range of conformance tests defined by the Joint Electron Device Engineering Council (JEDEC). The JEDEC specifications for the fifth generation of double data rate memory (DDR5) include an exhaustive list of conformance measurements and test cases required for transmitter compliance.
When testing your DDR5 devices, automate the calibration, setup, execution, and documentation of your compliance tests with purpose-built hardware and software. Ideally, use a high-bandwidth oscilloscope (25 GHz+) with a high effective number of bits, high-bandwidth probes designed for minimal effects on the measured signal, and interposer boards for probing as close to the silicon as possible. Couple this with software for test configuration, execution, evaluation, automation, and report-generation.
DDR5 transmitter compliance test solution
Ensuring interoperability of your DDR5 transmitter with other devices requires you to test it against JEDEC conformance standards. The Keysight solution for DDR5 transmitter compliance test consists of the UXR-Series real-time oscilloscope, InfiniiMax II probe, and D9050DDRC DDR5 compliance test software. Together, this hardware and software combination provides a holistic solution to ensure DDR5 devices meet the demanding requirements of the DDR5 specification.
The MX0023A InfiniiMax RC probe provides up to 25 GHz differential bandwidth and RC input impedance profile for extremely low midband loading necessary for modern high-speed probing requirements. Included is a wide variety of connectivity solution.
The D9050DDRC DDR5 Tx compliance test application software provides a fast and easy way to test, debug and characterize your DDR5 designs. DDR5 technology offers high data rate of up to 6.4GT/s which enables higher bandwidth for data transfer with lower power. The DDR5 Tx compliance software offers full test coverage to enable testing of transmitter physical layer of the DDR5 DRAM, data buffer and register chips.
