The new family of switches builds upon IDT’s leadership in high-performance, scalable PCIe Gen 1 and Gen 2 switches, supporting a capacity up to 64 lanes and 16 ports with additional protocol enhancements for improved efficiency and reduced power consumption.
IDT’s 89H64H16G3 is a 64-lane, 16-port Gen 3 PCIe switch, capable of up to 128 Gigabytes per second (GBps) switching capacity – the highest in the industry, making it the most scalable and highest-performance single-chip Gen 3 PCI Express solution on the market. The device conforms to the latest Gen3 PCIe specification providing 8Gbps link speed to enable the fastest PCIe connectivity possible for next generation enterprise server and storage systems. Added Gen 3 protocol enhancements improve overall efficiency and reduce power consumption, a critical factor for energy-conscious enterprise and cloud computing data centers. The device has been sampling to IDT’s lead customers for several months.
The new family of IDT switches also includes clock isolation, offering the ability to operate with independent spread spectrum clocks (SSCs), as well as multicast for a significant gain in performance. Moreover, the switch incorporates a multi-root partitioning feature that allows designers to reduce system cost by replacing multiple PCIe switches with a single monolithic solution.

The new switch family consists of the IDT 89H64H16G3, 89H48H12G3 and 89H32H8G3, which are 64/16, 48/12 and 32/8 port/lane counts, respectively. The devices are currently sampling to qualified customers and are available in 35 x 35 mm, 27 x 27 mm and 23 x 23 mm BGA packages.
