In master mode (SYSREF_REPEAT = 0), rising and falling edges at the SysRefReq pin are first reclocked to the fOSC, then fINTERPOLATOR, and finally to fOUT. A programmable number of pulses is generated with a frequency equal to fVCO / (2 × IncludedDivide × SYSREF_DIV_PRE × SYSREF_DIV). In continuous mode (SYSREF_PULSE = 0), the SysRefReq pin is held high to generate a continuous stream of pulses. In pulse mode (SYSREF_PULSE = 1), a finite number of pulses determined by SYSREF_PULSE_CNT is sent for each rising edge of the SysRefReq pin.
