PI90LV179 (Not Recommended for New Design (NRND))

Product Description

The PI90LV179is a differential line driver and receiver (transceiver) that is compliant with the IEEE 1596.3 SCI and ANSI/TIA/EIA-644 LVDS standards. This device uses low-voltage differential signaling (LVDS) to achieve data rates in excess of 660 Mbps while being less susceptible to noise than single-ended transmission.

The driver translates a low-voltage TTL/CMOS input into a lowvoltage (350mV typical) differential output signal. The receiver translates a differential 350mV input signal to a 3V CMOS output level.

Applications

Applications include point-to-point and multidrop baseband data transmission over a controlled impedance media of approximately 100 ohms. These include intra-system connections via printed circuit board traces or cables, hubs and routers for data communications; PBXs, switches, repeaters and base stations for telecommunications and other applications such as digital cameras, printers and copiers.
