Diodes Incorporated has introduced the PI7C9X3G808GP, a PCIe 3.0 packet switch with enhanced flexibility and performance. The new packet switch can deliver elevated performance parameters mandated by modern data centres, cloud computing, network-attached storage (NAS), and telecom infrastructure implementations.


Along with the ability to support 8-lane operations and accommodating 2-port, 3-port, 4-port, 5-port, and 8-port configurations, the new device also offers packet forwarding latency of less than 150ns (typical). The CDEP capabilities of the PI7C9X3G808GP support fan-out and dual-host connectivity. The low-power operating built-in PCIe 3.0 clock buffer helps in reducing the overall component count and BOM costs.


With three reference clock options (common, separate reference no spread (SRNS), and separate reference independent spread (SRIS)) and embedded multiple direct memory access (DMA) the device ensures efficient communication between hosts and connected endpoints.


The PI7C9X3G808GP also features error handling, advanced error reporting, and end-to-end data protection with error correction - key functionality in terms of reliability, availability, and serviceability (RAS). Under full load condition and 80°C junction temperature, the device will draw only 2.9W of power.


Packed in a 15mm x 15mm high-performance flip-chip package, with 196-ball BGA format, the PI7C9X3G808GP has a unit price of $20.13 in 1000 piece quantities.
