frequency can have an integer relationship with the VCO to avoid fractional spurs. Any APLL may accept any
other APLL as a reference instead of the XO. The BAW on APLL3 provides a good option for a high frequency
cascaded referenced.

The XO input of the LMK5C33216 has programmable on-chip input termination and AC-coupled input biasing
options to support any clock interface type.

For flexibility, the EVM provides the XO input options (use one at a time). C70 allows an external reference to be
provided at SMA connector XO_P (J8). C71 allows one of the on board XO/TCXO/OCXO footprints to be used.
By default Y1 is populated with a 38.88 MHz TCXO and selected with the populated R43. Other XO/TCXO/
OCXO may be installed and connected using the appropriate resistor. Care should be taken if more than one
device is installed to remove resistors for isolation.

Figure 3-10. XO Input

3.5.1 38.88-MHz TCXO (Default)

By default, the EVM is populated with a 38.88-MHz, 3.3-V LVCMOS, low-jitter TCXO (Y1) to drive the XO_P
input of the DUT with the onboard termination and AC coupling. See 

Figure 3-10

. Y1 can be used to evaluate

various frequency configurations.
