Description
The PI90LV032A, PI90LV028A, and PI90LV018A are
differential line receivers that use low-voltage differen-
tial signaling (LVDS) to support data rates in excess of
400 Mbps. These products are designed for applica-
tions requiring high-speed, low-power consumption
and low noise generation.
A differential input signal (350mV) is translated by the
device to 3V CMOS output level. Exclusive to the
PI90LV032A quad receiver is a power-down mode that
Three-states the outputs and places the device in a low-
power idle state (40mW typical).
Applications
Applications include point-to-point and multidrop
baseband data transmission over controlled imped-
ance media of approximately 100 Ohms. The transmis-
sion media can be printed circuit board traces,
backplanes, or cables.
The PI90LV032A, PI90LV028A, PI90LV018A and com-
panion line drivers (PI90LV031A, PI90LV027A, and
PI90LV017A) provide new alternatives to RS-232, PECL,
and ECL devices for high-speed, point-to-point inter-
face applications.
