IDT announces PCI Express switches optimized to solve system I/O connectivity challenges. The devices are PCI Express 1.1 compliant and deploy a broad range of lane/port configurations. The PRECISE family delivers switching bandwidth of 24 gigabytes per second (GBps) for the 48-lane/12-port switch. At the low-end, the 8-lane/5-port switch delivers 4 GBps throughput. Key design decisions, such as support for up to 2048-byte payloads, large internal buffers and a significant number of flow control credits enable these switches to offer maximum throughput. Each member of the PRECISE family has a dedicated evaluation and development kit for device testing and analysis, and system emulation. Each kit consists of a hardware evaluation board with representative upstream and downstream connectivity, and an IDT-developed, GUI-based software environment that enables the designer to tune system and device configurations to meet system requirements. Moreover, to ensure that each OEM system design is optimized for production and meets its time to market objectives, IDT provides customers with extensive, collaborative technical support including system modelling and signal integrity analyses, and schematic and layout review services.
