- Make JEDEC timing and voltage data input valid window measurement on DDR4 command and data signal
- Display eye contour up to 1e-21 and highlight eye contour of interest
SANTA ROSA, Calif., April 5, 2016
Keysight Technologies, Inc. (NYSE: KEYS) today introduced a new bit error rate (BER) contour analysis tool that helps memory designers perform DDR4 and LPDDR4 JEDEC compliance measurements. Designers are now able to make data valid window measurement with components of noise and jitter to ensure valid and accurate data transfer. The BER contour analysis tool is a capability added to the E2688A Serial Data Analysis software and runs on Keysight Infiniium S-Series, 90000A, V-Series and Z-Series oscilloscopes.
Historically, double data rate (DDR) has defined its timing specifications with a belief of a zero BER. Latest DDR technology offers data rates of 3.2Gb/s or higher. Each picosecond now matters and can be the difference in passing and failing bits. At these high data rates, noise and jitter affect the signal integrity. Measuring and understanding the components of noise and jitter can enable designers to maximize the margin to ensure valid and accurate data transfer. The timing parameters specific to the BER contour analysis in accordance to the JEEC specification are timing data input valid window (TdiVW) and voltage data input valid window (VdiVW).
"The new BER contour software tool uses accurate algorithm to measure jitter and noise to compute statistical measurement of the DDR data valid window," said Dave Cipriani, vice president and general manager of Keysight's oscilloscope business. "This helps customers quantify the bit error rate and ultimately increase the margin of the DDR memory system."
U.S. Pricing and Availability
The Keysight BER contour tool is available now as an added feature to the E2688A Serial Data Analysis/Mask Testing with Clock Recovery software which would require the N8823A EZJIT complete license. The E2688A tool is currently priced at $8,951 and the N8823A software is priced at $12,000.
