Application Information
There are a few common practices which should be implied
when designing PCB for BLVDS signaling. Recommended
practices are:
•
•
•
•
•
Use at least 4 layer PCB board (BLVDS signals, ground,
power and TTL signals).
Keep drivers and receivers as close to the (BLVDS port
side) connector as possible.
Bypass each BLVDS device and also use distributed bulk
capacitance. Surface mount capacitors placed close to
power and ground pins work best. Two or three multi-layer
ceramic (MLC) surface mount capacitors (0.1 µF, and 0.01
µF in parallel should be used between each V
ground. The capacitors should be as close as possible to
the V
Use the termination resistor which best matches the
differential impedance of your transmission line.
Leave unused LVDS receiver inputs open (floating)
