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.

Cardinal 1650 is engineered specifically for architectures requiring lower output swing or when using discrete laser driver components for specialty silicon photonics or VCSELs.
