DS92LV090A9 Channel Bus LVDS Transceiver April 2000 DS92LV090A 9 Channel Bus LVDS Transceiver General Description 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.
