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.

Notes:
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
