M80885RCA DDR5 Receiver

The Keysight Technologies, Inc. M80885RCA DDR5 receiver conformance and characterization software provides a fast and easy way to test, debug and characterize your DDR5 designs. DDR5 technology offers high data rates of up to 8.8 GT/s (or higher with MRDIMM), which enables higher bandwidth for data transfer with lower power. The M80885RCA offers full test coverage to enable testing of receiver physical layer of the DDR5 DRAM, memory controller, data buffer and register chips.

 Features

• Remote control of the main test instrumentation
• Automatically program your DUT into test mode for each test
• Automated calibration following the procedure recommended in the specification
• Automatic and unattended conformance testing and characterization measurements
• Quick and easy measurement results to assess the performance of your DUT without expertise in BERT and DDR5 standard
• Support for Data Analytics using KS6800A Data Analytics Web Service Software

Comprehensive Test Coverage

The M80885RCA DDR5 receiver test application allows you to use the M8020A and M8040A1 BERTs to perform automated testing and margin analysis on your DDR5 receiver design. The application automatically configures the J-BERT for each test and provides an informative test result. It includes margin analysis indicating how close your device comes to passing or failing each test parameter. The DDR5 receiver test application automates the measurement as specified in the specification, which helps to save test time and design cost.

Easy Test Definition and DUT Control

The test application enhances the usability of the Keysight M8020A and M5010A BERTs and Infiniium oscilloscopes for testing DDR5 devices which includes the DRAM, memory controller, register and data buffer. The Keysight automated test framework guides you quickly through the steps required to define and calibrate the test setup, perform the tests and view the test results. In addition to selecting the type of DUT and to put it into test mode, you can select categories of tests or select individual tests. The user interface is designed to minimize unnecessary reconnections, which will help save test time and minimize potential operator errors. You can save the tests results and configurations as project files and recall them for quick testing and review previous results.

Configurability and Guided Connection

The DDR5 compliance test application provides flexibility in your test setup. The application lets you define controls for critical test parameters such as termination voltage, amplitude and delay step sizes target BER ratio and target confidence level. Once you have configured the tests, the connection page will display the connection diagram for the test you have selected.

You can also specify the number of test trials and only stop running selected tests when the stop condition is met. The application will save the worst-case test result to help you track down the anomalies in your signals.

Comprehensive Result Analysis

In addition to providing you with measurement results, the DDR5 conformance test application reports how close your test results are to the specified test limit. You can specify the level at which warnings are to be issued. You are provided a full array of statistics for each measurement.

Test Setup Calibration

The DDR5 Rx test application supports automatic calibration of the test setup. All calibration steps are automated. The test application prompts the user when user interaction is required for connecting the test setup. Detailed connection diagrams and instructions are provided by the test application. Calibration results are visualized in the Calibration View Tab.
