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
IN
and
R
OUT
). The logic interface provides maximum flexibility as 4
separate lines are provided (D
IN
, DE, RE, and R
OUT
). The
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.
The receiver threshold is
±
100 mV over a
±
1V common-
mode range and translates the low swing differential levels
to standard (TTL/CMOS) levels.
