DS92LV040A 4 Channel Bus LVDS Transceiver
August 2002
DS92LV040A
4 Channel Bus LVDS Transceiver
General Description
The DS92LV040A is one in a series of Bus LVDS transceiv-
ers designed specifically for high speed, low power back-
plane 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 out-
puts 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 dif-
ferential 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
鹵
1V.
The receiver threshold is less than +0/鈭?0 mV. The receiver
translates the differential Bus LVDS to standard (LVTTL/
LVCMOS) levels. (See Applications Information Section for
more details.)
