3.2.4 SYSREF Example
RFoutB of LMX2572 can be used to generate or duplicate SYSREF signal. The output of RFoutB can be a
single pulse, series of pulse, or a continuous stream of pulses. These pulses are synchronous with the
RFoutA signal with an adjustable delay. To use the SYSREF capability, the PLL must be in SYNC mode
with VCO_PHASE_SYNC_EN = 1. Here is an example of Pulsed mode.
