Product Description

ThePI90LV179,PI90LV180,PI90LV050,andPI90LV051aredifferen-

tial line drivers and receivers (transceivers) that are compliant with

theIEEE1596.3SCIandANSI/TIA/EIA-644LVDSstandards.These

devices use 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 drivers translate a low-voltage TTL/CMOS input into a low-

voltage (350mV typical) differential output signal. The receivers

translate a differential 350mV input signal to a 3V CMOS output level.

The driver section can be independently set to a power-down and

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 communi-

cations; PBXs, switches, repeaters and base stations for telecommu-

nications and other applications such as digital cameras, printers

and copiers.
