SYNC_BYPASS
This bit selects one frame sync input signal to synchronize the frame sync output signal.
0: EX_SYNC1 is selected. (default)
1: When the T0 selected input clock is IN1_CMOS, EX_SYNC1 is selected; when the T0 selected input clock is
IN2_CMOS, EX_SYNC2 is selected;when there is no T0 selected input clock, no frame sync input signal is selected.
6 - 4
SYNC_MON_LIMT[2:0]
These bits set the limit for the external sync alarm.
000: ±1 UI.
001: ±2 UI.
010: ±3 UI. (default)
011: ±4 UI.
100: ±5 UI.
101: ±6 UI.
110: ±7 UI.
111: ±8 UI.

SYNC_PH2[1:0]
These bits set the sampling of EX_SYNC2 when EX_SYNC2 is enabled to synchronize the frame sync output signal. Nomi-
nally, the falling edge of EX_SYNC2 is aligned with the rising edge of the T0 selected input clock.
00: On target. (default)
01: 0.5 UI early.
10: 1 UI late.
11: 0.5 UI late.
1 - 0
SYNC_PH1[1:0]
These bits set the sampling of EX_SYNC1 when EX_SYNC1 is enabled to synchronize the frame sync output signal. Nomi-
nally, the falling edge of EX_SYNC1 is aligned with the rising edge of the T0 selected input clock.
00: On target. (default)
01: 0.5 UI early.
10: 1 UI late.
11: 0.5 UI late.
