DS92LV222A Two Channel Bus LVDS MUXed Repeater May 1998 DS92LV222A Two Channel Bus LVDS MUXed Repeater General Description The DS92LV222A is a repeater designed specifically for the bridging of multiple backplanes in a rack. The DS92LV222A utilizes low voltage differential signaling to deliver high speed while consuming minimal power with reduced EMI. The RSEL pin and DE pins allow maximum flexibility as to which receiver/driver are used. The DS92LV222A repeats signals between backplanes and accepts or drives signals onto the local bus. It also features a flow through pin out which allows easy PCB routing for short stubs between its pins and the connector. The driver is selectable between 3.5 mA (100Ω load) and 8.5 mA (27Ω load) output loop currents depending upon the level applied to the ISEL pin. This allows for single termination (point-to-point) and also double termination (multipoint) applications while maintain similar differential levels. The receiver threshold is ± 100 mV, while providing ± 1V common mode range.
