Blue Heron is a multiprotocol retimer which enables full recovery of a 40+dB 224G link. With Blue Heron, system integrators can architect rack-scale cable backplanes as well as flexible tray placement of GPUs and switch ICs to support AI scale-up applications.\n\n\nBlue Heron is built in an advanced 3nm process using Credo’s high-performance 224G SerDes. This SerDes incorporates an advanced 30-Tap FFE architecture and additional 16-Taps for reflection cancellation, enabling extended reach up to 40+dB for long-reach cable and PCB backplane applications.\n\n\n“The fast-growing scale-up market consists of a diversity of scale-up protocols such as UALink, ESUN and Ethernet which converge at layer 1 on the 224G 802.3 standard,” said Sandeep Shah, AVP of Product for Credo’s Retimer Products. “Credo’s leading Blue Heron 224G retimer can support all of these standards enabling a simple, multi-protocol solution for customers.”\n\n\n“UALink is experiencing rapid growth, demanding r...
