JAJSE32B October 2017 – January 2019 LMX2572
PRODUCTION DATA.
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. SYSREF output is triggered when there is a 0 → 1 transition at the SysRefReq pin. In SYSREF Pulsed mode, a maximum of 15 consecutive pulses can be generated at a time.
