Test Circuits and Timing Waveforms (Continued)

Typical Bus Application Configurations

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.
