7. Clock Output Circuits (OUTx/OUTxB)
Each of the eight outputs (four differential pairs) is ac-coupled to its respective SMA connector. The output clock termination circuit is
shown in the figure below. The output signal has no dc bias. If dc coupling is required, the ac coupling capacitors can be replaced with
a resistor of appropriate value. The Si5372-EVB provides pads for optional output termination resistors and/or low frequency capacitors.
Note:
Components with schematic “NI” designation are not normally populated on the Si5372-EVB and provide locations on the PCB
for optional dc/ac terminations by the end user.
