Digital ICs/DSPs: High-Bandwidth, Low-Voltage Operation Key To Bus-Switch Family

A novel series of eight NanoSwitch digital bus switches is destined for servers, RAID storage systems, Super VGA, memory-bank switching, and high-performance networking/telecom backplanes. The PI3CH family of low-voltage (2.5/3.3-V), high-bandwidth (500 MHz) bus switches simplifies the I/O migration from parallel to serial-differential signaling standards. Important performance features include very flat on resistance (5-Ω flat) across the full device bandwidth and low On/Off capacitance (5 to 10 pF), enabling the switches to minimize bus loading. The 5-V I/O tolerance and beyond rail-to-rail capability lets the switches bridge legacy 5-V I/O based platforms to new 2.5/3-V systems. Among the family devices are two-port versions with two, four, eight, or 10 channels and with 2:1 or 4:1 multiplexers/demultiplexers. Prices start at $0.50 each in lots of 1000.
