PCIe 3.0 packet switch has multi-host capabilities for edge computing

With 12 ports and 24 lanes, the PI7C9X3G1224GP PCIe 3.0 packet switch from Diodes can be used in edge computing, data storage, communications infrastructure and incorporated into host bus adapters (HBAs), industrial controllers and network routers.

The PI7C9X3G1224GP has a low packet forwarding latency of less than 150ns (typical). Ports can be configured using the ability to allocate variable lane widths to each port. For fan-out purposes, any port of the packet switch can be configured as upstream and connected to multiple downstream ports. Through cross-domain, end-point (CDEP) configuration of certain ports, it is possible for multi-host arrangements to be supported to boost performance and expand functionality, explained Diodes. 

The adaptive receive side and transmit side equalisation (RXEQ/TXEQ) features included assist with maintaining signal integrity levels and ensuring continued system stability.

The integrated PCIe 3.0 clock buffer simplifies designs and reduces the overall bill of materials (BoM) costs, claimed Diodes while power management capabilities make the PI7C9X3G1224GP suitable for system designs where energy saving gains are critical. The operational temperature is continuously monitored via the built-in thermal sensor. Error reporting and other diagnostic functions are also included.

The PI7C9X3G1224GP is supplied in a 324-pin flip-chip BGA package format.
