HMC 30G-VSR Compliance Kit

Open Live Script

Characterize and validate the performance of a hybrid memory cube (HMC) 30G-VSR channel design.

This kit is designed for analysis of an interface between a host ASIC and a Cube. The total channel length between devices is approximately 10 inches. The kit has sheets that represent network characterization for insertion and return loss testing and both single channel and multi-bit channel simulation sheets to measure BER compliance and RX stress testing. The kit includes schematics for testing 30 Gb/s, 28 Gb/s and 25 Gb/s operation including all applicable masks scaled for the representative bit rate.

This kit enables you to insert a channel design and characterize and validate its performance using the specification masks to determine if the channel has a “high confidence” of success. If the channel does not meet the compliance masks or BER estimates, further investigation or redesign, along with simulation, will need to be performed to determine possible changes to meet compliance.
