Pericom Semiconductor Corp., a supplier of high-speed ICs and frequency control devices, has released eight new NanoSwitch digital bus switch products that address the operational requirements of next-generation servers, RAID, Super VGA, memory bank switching, and high-performance networking and telecom backplanes.

The PI3CH family of low-voltage (2.5V/3.3V), high-bandwidth (500MHz) bus switches offer expanded performance capabilities that meet the challenges of advanced performance communication buses like PCI-X, as well as emerging DDR-I/DDR-2 memory standards, and also simplifies the I/O migration from parallel to serial differential signaling standards.

Jeff DeAngelis, director of product marketing, said, "This product line extension helps rejuvenate the design engineer's toolbox by offering new performance alternatives never believed possible in Digital Bus Switch technology."

Key performance features in this product family include a flat on-resistance (5-ohm flat) across the full device bandwidth, and low on/off capacitance of 5pF to 10pF that enables the switches to be used in applications to reduce bus loading. The 5V I/O tolerance and beyond rail-to-rail capability also makes the switches suitable for bridging legacy 5V I/O based platforms to next-generation 2.5V/3V systems.

The devices feature a signal passing bandwidth of 500MHz, beyond rail-to-rail switching, 5V I/O tolerant with 3.3V supply, 2.5V, and 3.3V supply voltage operation, and hot-insertion capability. Rated for operation between the -40C to 85C temperature range, the switches are housed in a variety of performance and space saving packaging ranging from TSSOP to ultra-compact TDFN. Pricing starts at 50 cents in 1,000 unit quantities.
