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 transceiv-
ers designed specifically for the high speed, low power pro-
prietary backplane or cable interfaces. The device operates
from a single 3.3V power supply and includes nine differen-
tial line drivers and nine receivers. To minimize bus loading,
the driver outputs and receiver inputs are internally con-
nected. 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 differ-
ential Bus LVDS (BLVDS) output levels. This allows for high
speed operation, while consuming minimal power with re-
duced EMI. In addition, the differential signaling provides
common mode noise rejection of
鹵
1V.
The receiver threshold is less than
鹵
100 mV over a
鹵
1V
common mode range and translates the differential Bus
LVDS to standard (TTL/CMOS) levels. (See Applications In-
formation Section for more details.)
