DS90LV019

3.3V or 5V LVDS Driver/Receiver

General Description

The DS90LV019 is a Driver/Receiver designed specifically

for the high speed low power point-to-point interconnect ap-

plications. The device operates from a single 3.3V or 5.0V

power supply and includes one differential line driver and

one receiver. The DS90LV019 features an independent

driver and receiver with TTL/CMOS compatibility (D

separate lines are provided (D

device also features a flow-through pin out which allows

easy PCB routing for short stubs between its pins and the

connector. The driver has 3.5 mA output loop current.

The driver translates between TTL levels (single-ended) to

Low Voltage Differential Signaling levels. This allows for high

speed operation, while consuming minimal power with re-

duced EMI. In addition, the differential signaling provides

common-mode noise rejection.

mode range and translates the low swing differential levels

to standard (TTL/CMOS) levels.
