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 Section for more details.)
