FEATURES  
DESCRIPTION  
The SCAN92LV090A 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.

IEEE 1149.1 (JTAG) Compliant  
Bus LVDS Signaling  
Low Power CMOS Design  
High Signaling Rate Capability (Above 100  
Mbps)  
0.1V to 2.3V Common Mode Range for VID

±100 mV Receiver Sensitivity  
Supports Open and Terminated Failsafe on  
Port Pins  
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.  
3.3V Operation  
Glitch Free Power Up/Down (Driver & Receiver  
Disabled)  
Light Bus Loading (5 pF Typical) per Bus  
LVDS Load  
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.  
Designed for Double Termination Applications  
Balanced Output Impedance  
Product Offered in 64 Pin LQFP Package and  
NFBGA Package  
This device is compliant with IEEE 1149.1 Standard  
Test Access Port and Boundary Scan Architecture  
with the incorporation 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).
