This bit selects one frame sync input signal to synchronize the frame sync output signals.
0: EX_SYNC1 is selected. (default)
1: When the T0 selected input clock is IN1_CMOS or IN1_DIFF, EX_SYNC1 is selected; when the T0 selected input clock
is IN2_CMOS or IN2_DIFF, EX_SYNC2 is selected; when the T0 selected input clock is IN3_CMOS, EX_SYNC3 is
selected; when there is no T0 selected input clock, no frame sync input signal is selected.
These bits set the limit for the external sync alarm.
000: ±1 UI.
001: ±2 UI.

011: ±4 UI.
100: ±5 UI.
101: ±6 UI.
110: ±7 UI.
111: ±8 UI.
These bits must be set to ‘1011’.
