Hello,
Let's work from Figure 6 in the datasheet:
Given:
- AC coupling capacitors on both sides of the switch
- A Tx common mode-voltage above 2V, and we'd like to bias it to something a little lower:
Questions:
1. What would be the values for the pull-up resistors? 50 Ohms, or something much higher.
2. Does the VBIAS source need to be low-impedance? Or can we use a simple resistor divider with a noise capacitor from the mid-point to GND?
