Cloud optimized SoC to enable low power AECs
Raon is a 4-Lane Uni-Directional CDR with complete reference design for 400Gbps AECs, with 25G NRZ and 56G PAM-4 per lane, up to 25dB channel loss compensation, while having ultra low power consumption.
Raon is a fully integrated single chip, 4-channel uni-directional CDR/Re-timer. Each lane supports 28G NRZ or 56G PAM-4 transmission, over a variety of media including optics, passive copper cables and backplanes. The device is optimized for Ethernet applications which are compliant with OIF CEI-56G-VSR and CEI-56G-MR specifications. Thanks to a fully optimized solution in CMOS technology, the power consumption is extremely low when compared to others. The device has built-in programmable and autonomous adaptive equalization in the receiver that compensates for transmission line losses and inter-symbol interference.
