MACsec / IPsec

Owl 400

The CMS42550 Owl 400 is a 400G MACsec with 400G LR Retimer / 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 delivery 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 Owl 400 supports bi-directional 400G (8 x 56G PAM4 <-> 8x56G PAM4 in Retimer mode and 8 x 56G PAM4 <-> 16x28G NRZ in a Gearbox mode) with MACsec. IPsec is available through a firmware update. It is pin compatible with the CMX42550 Sparrow 400G Gearbox. Other related products in this family include the Owl 800.

Owl 400 is cost effectively manufactured on TSMC’s mature 28nm process.
