General Description

The DS90LV019 is a Driver/Receiver designed specifically

for the high speed low power point-to-point interconnect applications.

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 (DIN and

ROUT). The logic interface provides maximum flexibility as 4

separate lines are provided (DIN, DE, RE, and ROUT). 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 reduced

EMI. In addition, the differential signaling provides

common-mode noise rejection.

The receiver threshold is ±100 mV over a ±1V commonmode

range and translates the low swing differential levels

to standard (TTL/CMOS) levels.
