Product Description
The PI90LVB179, PI90LVB180, PI90LVB050, and PI90LVB051 are
differential line drivers and receivers (transceivers) that are similar
to the IEEE 1596.3 SCI and ANSI/TIA/EIA-644 LVDS standards (the
difference is that the driver output current is doubled). This modi-
fication enables true half-duplex operation with more than one LVDS
driver or with two line transmission resistors over a 50 ohm differen-
tial transmission line. 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 into a 50-ohm load.
The receivers translate a differential 350mV input signal to a 3V CMOS
output level. Driver section can be independently set to a power-down
and high-impedance output mode with the D
Receiver section is controlled by the R
Applications
Applications include point-to-point and multidrop baseband data
transmission over a controlled impedance media of approximately 50
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.
