I used ds90ub934 deserializer to deseria the camera(OV10635+DS90UB913)。all i2c communication is ok,and D2-D9 of ds90ub934 have got datas,but HSYNC and VSYNC keeps low.(HSYNC\VSYNC of ds90ub913 is ok ).How do i check my design?

Hi Palaniappan!
Thank you for your reply,I tried to set up the TI934 & TI913 work in 12-bit LF mode,The signal of HSYNC/VSYNC are ok.But the ov10635's pclk is 96MHz and output 10-bit YUV,so I need to set TI913 & TI934 work in 10-bit raw mode,in 10-bit raw mode TI913 has normal HSYNC/VSYNC,however TI934 havs no HSYNC/VSYNC(PCLK and RXOUT0-RXOUT9 are all fine)。
Yes, I think so as well. for such issue, it is much more likely the hardware design issue not chip level issue.
