DS92LV1212A: Connecting DS92LV1212A to AM5728 (BeagleBoard-X15)

Aleksandr Shateljuk

Part Number: DS92LV1212A

Hello everyone, I have a problem. I want to connect DS92LV1212A (parallel interface) to AM5728 VIP interface. I will use Beaglebone X15, I make a board for connecting CMOS sensor MT9V022 (www.onsemi.com/.../MT9V022-D.PDF) In datasheet provided application when for connections uses next signals frame, control, and 8bit data bus, I want to connect it to vsync , hsynk and 8bit bus VIP interface AM5728 CPU. But in pinout diagram, I see 10bit data bus and did not find frame and control pins. Can any help me with it? How I need connect it properly?

Hello,
I assume you are connecting a serializer such as DS90LV1021 with the DS92LV1212A right? These two devices do not have a dedicated Frame and Control pin.

Data send to the Serializer DIN[0:9] will get outputted from the corresponding Deserializer ROUT[0:9].

In your case, you could send VSYNC data to Serializer DIN[0], and HSYNC data to Serializer DIN[1], then VSYNC will be outputted from ROUT[0], and HSYNC will be outputted from ROUT[1].

Best Regards,
Charley Cai

No, I need to connect MT9V022 to DS92LV1212A, like in datasheet for CMOS sensor (see attached photo). But I do not understand what pins need to connect to Line and frame valid

It looks like in stand-alone mode and 8bit pixel mode, the CMOS sensor is sending data in this format. Line_Valid will appear on ROUT[8], and Frame_Valid will appear on ROUT[9].
