Menlo Micro's MM5625 is an Ideal Switch-based, fully integrated differential DP3T loopback module built for asymmetric SerDes test benches, delivering 80 Gbps (20 GHz) bandwidth so PCIe Gen5/Gen6 and other PAM4 links can be routed, looped back, or isolated without bulky relays. The IMS 2025 launch and the product brief detail its 12-port topology, 128 switch states, on-board charge pump/SPI control, and billions of switching cycles that drastically shorten AI/GPU validation timelines while fitting inside an 8.2 x 8.2 mm LGA SiP.
