1.6T LRO Optical DSP

200G per lane Optical DSP

Cardinal 1650

The Cardinal 1650 optical DSP is an 8-channel 224 Gbps-per‑lane PAM4 DSP purpose-built for 1.6 Tb/s linear receive optics (LRO) transceivers. LRO transceivers offer a compelling, low-power alternative for next‑generation AI fabrics, supercomputing clusters, and hyperscale data centers.​

Built on advanced 3nm CMOS technology and leveraging Credo’s proprietary high‑performance design techniques, the Cardinal 1650 provides industry‑leading power efficiency, ultra‑low latency, and exceptional signal integrity. Cardinal 1650 is engineered specifically for architectures requiring lower output swing or when using discrete laser driver components for specialty silicon photonics or VCSELs.
