...reference (see Figure 8). If HMS=1 then the ZL30100 will transition to Normal mode via the TIE correction state andthe phase difference between the output signals and the selected input reference will be maintained.When the ZL30100 is operating in Normal mode, if it determines that its selected reference is disrupted (Figure 3)then its state machine will cause it to automatically go to Holdover mode. When the ZL30100 determines that its... ...ZL30100 is based on the inputs MODE_SEL1:0, REF_SEL and HMS.3.7 Master ClockThe ZL30100 can use either a clock or crystal as the master timing source. For recommended master timingcircuits, see the Applications - Master Clock section.... ...ZL30100 Data Sheet4.4.2 Holdover Mode Holdover mode is typically used for short durations while network synchronization is temporarily disrupted.In Holdover mode, the ZL30100 provides timing and synchronization signals, which are not locked to an external... |
