The SysRef can be used in a repeater mode, which just echos the input, after being re-clocked to the fINTERPOLATOR frequency and then RFout, or it can be used in a repeater. In repeater mode, it can repeat 1,2,4,8, or infinite (continuous) pulses. The frequency for repeater mode is equal to the RFout frequency divided by the SYSREF divider.
