SAN JOSE, Calif.Designed to support the bandwidth requirements of next-generation wireless and networking infrastructures, Integrated Device Technology Inc. has developed multi-port devices that offer both the x36 QDR-II or x18 LA-1 QDR-II interfaces, and a family of x72 synchronous dual-port devices.
The IDT QDR-II dual-port devices are available in both 9- and 18-Mbit densities and deliver 250 MHz clock speed and 36-Gbits/s in total throughput. Dual-port products are used to facilitate communications between multiple processors by way of two ports integrating memory and logic control, enabling the processors simultaneous access to a common central memory.

The IDT QDR-II dual-port devices support the necessary aggregate bandwidth common in 10-Gbits/s applications, while satisfying the needs of networking equipment and module designers who are seeking to realize faster communications between multiple processors. The products also offer a 1.8-volt core and selectable 1.4- and 1.9-volt I/O options for voltage matching between two separate domains. HSTL I/O options are also available to support differing clock frequencies.
Delivering 166-MHz performance, the IDT x72 18-Mbit (256Kx72) and 9-Mbit (128Kx72) dual-port devices support the 64-bit memory interfaces found in next-generation DSPs. Synchronous functions include full-boundary counters, multiple independent chip and byte enables, collision detect signal and synchronous interrupts.
They are also equipped with an optional sleep mode on both ports, which allows the product to minimize power consumption by placing the part in full standby mode without any input-level restrictions.
Pricing starts at less than $90.00 for 10K volumes. All products are sampling now.
