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 (100 load) and 8.5
mA (27
level applied to the ISEL pin. This allows for single termina-
tion (point-to-point) and also double termination (multipoint)
applications while maintain similar differential levels.
The receiver threshold is
common mode range.
