Notes:

1) It is recommended that the VTERM pins from multiple inputs NOT be tied together, unless driven from a low impedance

supply.

2) The reference clock receivers have self-biased inputs.

3) For unused reference clock receivers, it is recommended to tie one side low by connecting a 1k Ohm resistor to Vee, and

letting the other side float.
