DS90UB913Q/914Q timing limitiation hsync vsync



Hi,

In the application I currently building up, the HSYNC and VSYNC pins are not used for the synchronization.
But I need some additional GPI's (on 913Q) much faster then I²C.

If I use HSYNC and VSYNC for fast data transmission, nearly the same data-rate as my parallel data, i get wrong data output on 914Q.
If I reduce the data rate of HSYNC and VSYNC up to 1/512 or 1/1024 of parallel data. It works very well.

The Question is:
Do I have to follow some special timing (maximal data rate) requirements on HSYNC and VSYNC?

Thanks
