Description
The PI90LV179, PI90LV180, PI90LV050, and PI90LV051 are differen-
tial line drivers and receivers (transceivers) that are compliant with
the IEEE 1596.3 SCI and ANSI/TIA/EIA-644 LVDS standards.
These devices use low-voltage differential signaling (LVDS) to
achieve data rates in excess of 660 Mbps while being less suscep-
tible 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 high-impedance output mode with the D
EN
pin (active HIGH).
The receiver section is controlled by the R
EN*
pin (active LOW).
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 telecom-
munications and other applications such as digital cameras, printers
and copiers.
