Description
The PI90LV031A, PI90LV027A, and PI90LV017A are differential
line drivers that use low-voltage differential signaling (LVDS)
to support data rates in excess of 400 Mbps. These products are
designed for applications requiring high-speed, low-power con-
sumption and low noise generation.
A low voltage TTL/CMOS input level is translated by the device
into a low-voltage (350mV) differential output signal. Exclusive to
the PI90LV031A quad driver is a power-down mode that 3-states
the outputs and places the device in a low-power idle state (13mW
typical).
Applications
Applications include point-to-point and multidrop baseband data
transmission over controlled impedance media of approximately
100 ohms. The transmission media can be printed circuit board
traces, backplanes, or cables.
The PI90LV031A, PI90LV027A, PI90LV017A and companion
line receivers (PI90LV032A, PI90LV028A, and PI90LV018A)
provide new alternatives to RS-232, PECL, and ECL devices for
high-speed, point-to-point interface applications.

Note:
Stresses greater than those listed under Abso-

damage to the device. This is a stress rating
only and functional operation of the device
at these or any other conditions above those
indicated in the operational sections of this
specification is not implied. Exposure to abso-
lute maximum rating conditions for extended
periods may affect reliability.

1. “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that
the devices should be operated at these limits. The table of “Electrical Characteristics” specifies conditions of device operation.
2. Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground except:
V
Od1
and
DV

.
3. All typicals are given for: V
CC

A

4. The PI90LV031A/PI90LV027A/PI90LV017A are current mode devices and only functions within datasheet specifications when a resistive
load is applied to the driver outputs typical range is (90W to 110W).
