3.5.3 Behaviour on Loss and Re-acquisition of the Reference Signal
By default, the GS4901B/GS4900B will ignore one missing H pulse on the HSYNC
pin and will continue to operate in Genlock mode (although the LOCK_LOST pin
will temporarily be set HIGH). This behaviour is controlled by the Run_Window bits
of register address 24h.
If there are two consecutive missing H pulses on the HSYNC input pin, the
REF_LOST and LOCK_LOST pins will both go HIGH and the device will enter
Freeze mode. An internal flywheel ensures the selected output clock and timing
signals maintain their previous phase and frequency and continue to operate
without glitches.
The VSYNC and FSYNC signals are not monitored in Genlock mode; loss of signal
on these pins will not affect the operation of the device.
NOTE 1: If the input reference is removed and re-applied, all line-based timing
outputs will be inaccurate for up to one frame for all output standards.

‘X’ signifies ‘don’t care.’ The X bit will be ignored when determining which standard to select in each of the 6 groups above.
NOTE: When the SD input reference format of 720x483/59.94/1:1 (VID_STD = 9) is applied to the input, the user must set bit [15] of the of the
Amb_Std_Sel register address to '1' before the device will recognize this reference.
