The IDT CPS-1848 provides a full, non-blocking bandwidth of 240 Gbps for up to 18 logical ports. The CPS-1848 device utilizes a 5th generation switch fabric, building upon Gen1 CPS and Tsi switching architectures. This new switch uses patent pending features to minimize latency, ensure scheduling fairness, and provide superior multicast throughput. The CPS-1848's 6.25 Gbaud SerDes is ideal for backplanes, yet can run even lower power for local connectivity.This performance is realized over twice the transmission channel distance and three orders of magnitude improvement in bit error rate (BER) compared to the very capable Gen1 standard.
