PCIe Switching Solution Optimized For The Communications Market is a first says IDT

Comprised of three 16-port devices, the family offers lane-count options of 16, 22 and 34 PCIe lanes. The 16-lane, 16-port 89HPES16H16 offers economical, high port-count connectivity for control plane traffic between management processors, ASICs, FPGAs and I/O peripherals. The 22-lane, 16-port 89HPES22H16 and 34-lane, 16-port 89HPES34H16 offer flexible x8, x4 and x1 port configurations to support a mix of data and control plane traffic. The large port widths also enable efficient, high-performance cascading connectivity for switching complexes with more than 16 ports, and provide for redundancy and failover mechanisms.

The new IDT switching solutions offer a suite of features that enable communications system architects to leverage PCIe’s power savings, scalability and cost advantages as a primary system or backplane interconnect. Each of the new devices features redundant upstream ports for multi-root support and failover, support for sophisticated quality of service with two virtual channels, and deterministic latency at full wirespeed throughput, ensuring predictable performance for critical system control and data plane traffic.

The new devices are available in flip chip BGA packages as small as 23mm with 1mm ball spacing. Each of the IDT PCIe switching solutions has a dedicated evaluation and development kit for device testing and analysis, and system emulation. IDT also provides customers with extensive, collaborative technical support, including system modelling and signal integrity analyses, and schematic and layout review services.
