PLL Clock Output
The PLL clock output pin (CLK_OUT) provides a buffered version of the output of the frequency synthesizer.
The driver can be set to high-impedance with the ClkOutDis bit.
The output from the PLL automatically drives a static low condition while the PLL is un-locked (when the
clock may be unreliable). This feature can be disabled by setting the ClkOutUnl bit, however the state
CLK_OUT may then be unreliable during an unlock condition.
Auxiliary Output
The auxiliary output pin (AUX_OUT) can be mapped, as shown in
ence clock (RefClk), input clock (CLK_IN), additional PLL clock output (CLK_OUT), or a PLL lock indicator
(Lock). The mux is controlled via the AuxOutSrc[1:0] bits. If AUX_OUT is set to Lock, the AuxLockCfg bit is
then used to control the output driver type and polarity of the LOCK signal (see
If AUX_OUT is set to CLK_OUT the phase of the PLL Clock Output signal on AUX_OUT may differ from the
CLK_OUT pin. The driver for the pin can be set to high-impedance using the AuxOutDis bit.
