SCAN92LV090
9 Channel Bus LVDS Transceiver w/ Boundary SCAN
General Description
The SCAN92LV090A is one in a series of Bus LVDS trans-
ceivers designed specifically for the high speed, low power
proprietary backplane or cable interfaces. The device oper-
ates 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 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 ±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.
This device is compliant with IEEE 1149.1 Standard Test
Access Port and Boundary Scan Architecture with the incor-
poration of the defined boundary-scan test logic and test
access port consisting of Test Data Input (TDI), Test Data
Out (TDO), Test Mode Select (TMS), Test Clock (TCK), and
the optional Test Reset (TRST).
