DESCRIPTION

The DS92LV090A is one in a series of Bus LVDS

transceivers designed specifically for the high speed,

low power proprietary backplane or cable interfaces.

The device operates from a single 3.3V power supply

and includes nine differential line drivers and nine

receivers. To minimize bus loading, the driver outputs and receiver inputs are internally connected. The

separate I/O of the logic side allows for loop back

support. 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 translates 3V TTL levels (single-ended) to

differential Bus LVDS (BLVDS) output levels. This

allows for high speed operation, while consuming

minimal power with reduced EMI. In addition, the

differential signaling provides common mode noise

rejection of ±1V.

The receiver threshold is less than ±100 mV over a

±1V common mode range and translates the

differential Bus LVDS to standard (TTL/CMOS)

levels. (See Applications Information Section for more

details.)
