Other Parts Discussed in Thread: TVP5150, TVP5150AM1, TVP5150AM1-EP

Attached is the overview of the project

In my project the camera will be mounted 1.5 meter apart from the mcu so we are using camera module with ntsc output beacuse parallel interface is not possible for 1.5 metre.

We though to use TVP5150 ,But it was found(NRND),Is there any alternative for TVP5150 so we can proceed our project,

If there is no alternative can you suggest any suitable solution.The objective is to get the video stream from 1.5mtr to 32bit mcu

    NRND does not mean it is obsolete.

    NRND simply means that design support is limited.

    There are currently no plans to discontinue the TVP5150.

    I would, however, suggest using the TVP5150AM1 which is a slightly more recent ROM revision.

    You can also use the TVP5150AM1-EP which is not in NRND state.

    Thanks for reply.

    TVP5150 as i mentioned in block diagram of previous query -Is it good choice  for my project ??or should i use serializer and deserializer chip.

    My microcontroller is 168MHZ ARM core M4 with DCMI (parallel camera input).

    Kindly give comment with reason to choose among TVP5150 and serializer and deserializer i am designing Rear view camera module

    There are a million different ways to achieve this, each have their own advantages and disadvantages.

    For example, you could simply use a USB camera. This solution will allow many different resolutions/frame rates etc... Is simple and often the host processor already has drivers. It is also more expensive.

    Using CVBS video will be cheaper, but the video quality will be limited to 720x480 interlaced video with low quality CVBS encoding. Then you will need to get the data from the camera to the processor, so serializing somehow is likely needed. There are a few different serializer options including SDI, LVDS etc...

    Higher quality cameras can't use CVBS so you will need a higher quality converter and serializer.

    I would start by specifying your minimum quality requirements, then work from there.
