4.14 H:V:F Timing Signal Extraction
The GS3471 extracts critical timing parameters from the received TRS words.
Horizontal blanking (H), Vertical blanking (V), and Field odd/even (F) timing are output
on the STAT[2:0] pins by default.
The H signal timing can be selected through GSPI using the H_CONFIG parameter. By
default, the H signal timing is set to active line blanking. This can be changed to TRS
based blanking by setting the H_CONFIG parameter to 1.
The timing of these signals is shown in Figure 4-10 through Figure 4-15.
Note: Both 8-bit and 10-bit TRS words are identified by the device.
Figure 4-10: H:V:F Output Timing - 3G Level A and HD 20-bit Mode
Figure 4-11: H:V:F Output Timing - 3G Level A and HD 10-bit Mode
