TVP5150AM1: TVP5150AM1 as a video encoder

Part Number: TVP5150AM1

Hi Team,

one of my customer is using our TVP5150AM1 and has now a question related this part.


In our current project we use the TVP5150AM1 as a video encoder for encoding a composite signal.

In this case the TVP5150AM1 was connected to the digital camera interface of the STM32H743.

Due to the data sheet of the TVP5150AM1 available to us, we could not clearly assign the output format of the TVP5150AM1.

The TVP5150AM1 is currently set to the output format "8-Bit 4: 2: 2 with discrete syncs".

However, our further processing in the controller does not produce a meaningful result.


On the one hand, the transmitted color format YCbCr is unclear and we cannot assign the order in which the color channels are arranged (e.g. YCbYCr or CbYCrY (for 4: 2: 2)).

Furthermore, certain sync signals do not seem to be transmitted correctly to the camera interface. As a result, a stable image cannot be stored.


Is there a more detailed description regarding the output format that describes the data in more detail?

We initialized the TVP5150AM1 according to "Example 2" in the data sheet and adapted the input signal to our requirements. Are there any other settings here that we need to consider?


Could you please help in this case
