Menlo Micro releases high-speed differential loopback switch
Menlo Microsystems has announced the release of its 4th high-speed differential loopback switch, the MM5625. Building off previous Menlo Micro loopback products, the MM5625 is optimised for asymmetric SerDes bus testing, supports 80Gbps PAM4 data-rates required for numerous emerging SerDes standards, and upgrades the RF performance across all 12 ports.
Based on Menlo Micro’s Ideal Switch technology, the MM5625 builds off the enormous success of the award-winning MM5620 loopback relay introduced in 2023. Since its debut, Menlo Micro’s loopback switch technology has been widely adopted by the world’s top suppliers of GPUs for AI, APUs for mobile, and other high-performance compute (HPC) platforms. It was designed to drastically simplify the challenges with testing asymmetric SerDes buses which have (1) TX port connected to (2) RX ports, or vice versa. By increasing the RF bandwidth across all 12 channels, and going from 16 to 128 possible control states, the MM5625 is enabling unprecedented levels of test coverage for a wide variety of high-performance semiconductor devices. Key applications include IC wafer sort, final test and test equipment for datacenter/AI GPU/CPU, APU, re-timers, network processors, and high-speed memory products.
Key features of the MM5625 include:
• DC to 20 GHz range, Low Insertion Loss: -2.7dB @ 20 GHz
• DP3T (differential mode) with Loopback Mode, 12 inter-connected high-speed ports
• Fully configurable with 128 connection different schemes
• Integrated charge pump driver, no external biasing circuitry required
• High Reliability: Greater than 3 billion switching operations
• Low-profile 8.2 x 8.2 mm LGA surface-mount package
