The CMR52241 Osprey 400 is a 400G MACsec with 400G LR Retimer and 400G Gearbox modes suitable for both backplane and front panel applications including cloud-scale switches, high-density routing platforms, and advanced server NIC cards.
The device has Credo’s innovative SerDes technology at its core to deliver the bandwidth, scalability, and end-to-end signal integrity at low power needed to meet the demands of advanced networks up to 800G with single-lane 28G, 56G, or 112G connectivity.
The NIST-certified Osprey 400 supports bi-directional 400G dual modes (8 x 56G PAM4 <-> 8x56G PAM4 Retimer and 8x56G PAM4 <-> 16x28G NRZ Gearbox) with MACsec and has expanded support for SM4 and IPsec.
The device is cost-effectively manufactured on TSMC’s mature 12nm process, reducing power by 40% compared to the previous family and is pin compatible with Owl 400 (CMS42550).
