4.12.2.2 Hsync Output Pin Mode
4.12.2.3 FIELD Output Pin Mode
For all output standards, the Vsync output signal changes twice per frame. The Vsync signal (pin
34) can be generated at the output in one of two modes:
Note that the output standard depends on the input TV standard and the programmable Normal
Pixel or Square Pixel mode.
The VSYNC output mode is selected by the VSYNCTYPE bit in the
The V bit of the output flow always changes at the beginning of the line (in compliance with standard
ITU-R BT 656).
Non-Interlaced mode: When required, the STV2310 is able to interlace the output, even if the
source is non-interlaced (by default, the output Vsync follows the input Vsync).
The Hsync output pulse can shifted, this is in comparision with the embedded Hsync pulse.
The FIELD output pulse represents the parity of the field and toggles either with the embedded
FIELD pulse, or is synchronous with the Vsync pin, when set in analog interlaced mode. To toggle in
analog interlaced mode, the direct parity mode must be selected.
1 “Digital“ Vsync mode: The VSYNC signal always changes at the beginning of the line,
2 “Analog” Vsync mode: The VSYNC signal changes either at the beginning or the middle of the
