Hi Sirs,
We suffer a issue : UB964 cann't output
May you please help to give us some suggestion . thank you very much.
The architecture is as the following:
1. AR0144 (PCLK 74.25Mhz 12bits parallel mode) -> UB913 ->UB914
2. DS90UB913A/914A Operation with Pixel Clock from Imager as Reference Clock.
3. We configure the UB964 as 12 bits high speed mode.
4. Before the sensor is streaming(no PCLK to UB913), we can access UB913 and finish the sensor registers's configure.
But after we let sensor stream on( provide PCLK to UB913) we cann't access both UB913 and sensor anymore(via I2C ), and there are no signal out in all UB914 PCLK /Hsync/Vsync.
At that moment the value of UB914's register 0x1c will change to 0x02(means no lock) from 0x03(before the PCLK is provided)
5. We cehck sensor out (i.e. UB913 input) , it do have the PCLK /HSync /Vsync signal and looks like that the format is ok.
Would you please help to give us some advise according to your experience? thank you very much
