DESCRIPTION
The DS92LV040A is one in a series of Bus LVDS
transceivers designed specifically for high speed, low
power backplane or cable interfaces. The device
operates from a single 3.3V power supply and
includes four differential line drivers and four
receivers. To minimize bus loading, the driver outputs
and receiver inputs are internally connected. 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 LVTTL levels (single-ended)
to differential Bus LVDS (BLVDS) output levels. This
allows for high speed operation while consuming
minimal power and reducing EMI. In addition, the
differential signaling provides common mode noise
rejection greater than ±1V.
The receiver threshold is less than +0/−70 mV. The
receiver translates the differential Bus LVDS to
standard (LVTTL/LVCMOS) levels. (See the
Applications Information Section for more details.)
