lvds common mode voltage
Hi,
LVDS driver and receiver pose both high-impedance nodes to common-mode signals which cuople into the differential line (on the TX there are current sources - on RX MOSFET gates) - so my question is - how are the common mode sdisturbances "damped"/"rejected" - the reflection factors are in no way as good as for the the differential signal (which see at least on the receiver side a differential termination resistor).
So what happens to common-mode disturbances in LVDS-signaling ?
