106G per Lane Optical DSP

Dove 400

The DOVE Platform Optical DSPs are designed for optical interconnect of Hyperscale/enterprise data centers, Cloud service providers, wireless service providers, and high-speed data network applications. The DOVE Platform includes DSPs for 100G/200G/400G optical interconnects.

Credo’s proprietary PAM4 DSP architecture minimizes die size and utilizes mainstream silicon process technology to deliver optimal cost, power, and performance for the next generation of optical modules. Pluggable optical modules with Credo PAM4 DSPs enjoy the lowest cost-of-ownership and industry-leading performance, while using minimal power.

Dove 400 (CFD60101) is used in the next generation of low power, high performance OSFP and QSFP-DD optical modules that support 400GbE DR4, FR4 and LR4 applications with PAM4 modulation.
