Frequently asked questions

How do I configure the board for OC-48 normal operating mode?

Set all switches S1 through S9 to the 0 position to use the on-board 19.44 MHz crystal as the reference clock.

What is the minimum differential input voltage required?

The input signal must provide a differential input of greater than 10 mV.

How do I select an external reference clock?

Set REFSEL switch S1 to 1 to disconnect the on-board oscillator and connect an external clock to the REFCLKP/REFCLKN pins.
