Si5340-EVB
8. Clock Output Circuits (OUTx/OUTxB)
Each of the 8 outputs (4 differential pairs) is AC coupled to its respective SMA connector. The output clock
termination circuit is shown in Figure 5 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 Si5340-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 Si5340-EVB and provide locations on
the PCB for optional DC/AC terminations by the end user.
