9 Channel Bus LVDS Transceiver

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.)
