FEATURES
DESCRIPTION
The SCAN92LV090A 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.

Light Bus Loading (5 pF Typical) per Bus
LVDS Load
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.
