Menlo MM5625 80Gbit/s PAM4 loop-back switch

“MM5625 delivers over 100 different configurations for the most complex SerDes bus test challenges,” according to the company.

It has 12 channels and has 128 possible control states compared with 16 for the company’s earlier products.

Bandwidth is dc to 20GHz range, with -2.7dB insertion loss at 20GHz.

Packaging is 8.2 x 8.2 m LGA, and an integrated charge pump driver removes the need for external biasing circuitry.

Durability is “Greater than three billion switching operations”, said Menlo.

Very little else has released about this chip – Electronics Weekly has requested a data sheet.

Use is expected in wafer sorting and test equipment for data centre chips including processors, re-timers and memories.
