7. Clock Output Circuits (OUTx/OUTxB)
Each of the eight output drivers (four differential pairs) is ac-coupled to its respective SMA connector. The output clock termination cir-
cuit is shown in
Figure 7.1 Output Clock Termination Circuit on page 9
below. The output signal will have no dc bias. If dc coupling is
required, the ac coupling capacitors can be replaced with a resistor of appropriate value. The Si5396J-A-EVB provides an L-network at
OUT0/OUT0B output pins for optional output termination resistors. Note that components with schematic “NI” designation are not nor-
mally populated.
