Part Number: DS90UB913A-Q1
Other Parts Discussed in Thread: DS90UB960-Q1

Hi,

I am trying to explore how to connect sensor to DS90UB913A-Q1 serializer with sensor having following control signals.

1. Vsync

2, PCLK

3. Href

4. 12 bit DVP data.

and DS90UB913A-Q1  having following

1. Vsync

2. PCLK

3. Hsync

4. 12 bit DVP data.

Regards,

Hardik Shah

    What deserializer are you using? If you are using 914A or 934 and run the devices in 12 bit mode, there is no restriction on what control signal you are sending. The deserializer will pass the same signal to processor, and it is up to the processor to process the signal.

    If you are using 954 or 964, there might be an issue and I would need a little more information on the timing of Href signal.

    I am using DS90UB960-Q1  deserializer. Please let me know if this will work?

    When using 913A with 960, HSYNC timing is used to control the creation of CSI line packet.
    If you need to use Href, please make sure Href signal follows the timing requirement in 960 datasheet 7.4.12 RAW Mode LV / FV Controls section.
    In addition to that, please make sure Href is inactive for at least 12 PCLK cycle between two Href pulses.
