RapidIO Switch

The CPS-1848 provides a full non-blocking bandwidth of 240 Gbps on up to 18 logical ports. The CPS-1848 uses a 5th generation switch fabric, building upon Gen 1 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. IDT’s Gen2 switches connect the Serial RapidIO ecosystem, including full backward compatibility to RapidIO 1.3 systems and components. The Serial RapidIO ecosystem enables carrier-grade reliable, fault tolerant systems with four standard traffic priority levels for quality of service. It also offers best-in-class messaging and atomic transaction support with protocol throughput efficiencies superior to other leading embedded interconnect protocols.
