Optical DSPs
Credo’s high‑performance, energy‑efficient PAM4 optical DSPs are designed for the demands of hyperscale data centers and AI compute fabrics. They deliver reliable, ultra‑low‑latency performance and strong network resiliency, while Credo’s low‑power SerDes architecture provides industry‑leading energy efficiency.
Credo’s portfolio supports fully retimed optical transceivers, Linear Receive Optics (LRO) modules, and active optical cables from 50 Gb/s to 1.6 Tb/s, enabling flexible optical architectures for diverse network deployments.
Maximum Flexibility,
Minimal Complexity
Unlike traditional 800G DSP solutions, the Robin DSP is offered in an exceptionally compact BGA package, giving system designers maximum flexibility without the complexity, risk, and high cost that come with bare-die approaches.
Optical DSP products
Credo’s extensive optical portfolio includes DSPs for 50G, 100G, 200G, 400G, 800G and 1.6T PAM4 optical transceivers and active optical cables.
