Description
The PI90LV179is a differential line driver and receiver (trans-
ceiver) 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 low-
voltage (350mV typical) differential output signal. The receiver
translates a differential 350mV input signal to a 3V CMOS out-
put level.
Applications
Applications include point-to-point and multidrop baseband data
transmission over a controlled impedance media of approxi-
mately 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 telecommunications and other applications such as digital
cameras, printers and copiers.
