6 Repeater Sync Mode

  1. SYSREF_MODE is made 3 Figure 6-1 shows the repeated synced output on Secondary1 sysrefout2_p(red) and Secondary2 sysrefout2_p(green) from Primary sysrefout2_p(yellow).
  2. Major difference between Figure 6-1(repeater sync) an Figure 5-2 (repeater non-sync) is that in repeater sync mode, pin3 is synced with the input clock and 2 delay clock cycles is seen. In this example, Clock input is 1GHz, so extra delay of 2ns is expected.
