TVP5150AM1: Analog input range of video decoder

Part Number: TVP5150AM1

Hi,

We need to use a decoder ic for our camera module CS0313-PB,

the camera output is "Composite Video signal: 1.0Vp-p, 75 ohms".

we are planned to move with TVP5150, but its maximum analog input range is 0-0.75 VPP.

i think it is difficult to interface both devices, Could you please suggest any suitable part or any solution?

Regards

    Hi Steve,
    Thank you for the response!

    Is there any importance of resolution or frame rate?

    Yes, but the camera appears to convert from the sensor format to standard PAL/NTSC so the sensor characteristics are not important regarding the output video.

    PAL and NTSC have very specific active resolutions, line rates, frame rates and interlacing so as long as the camera converts from the sensor characteristics into a standard format then it doesn't matter. All we care about is the output analog format.

    What you MIGHT see is that there are black regions to the left/right/top/bottom edges but this depends on whether the camera scales the 640x480 to NTSC/PAL frame sizes or not. If the camera does not do any scaling then you might need to use the target processor to scale, but it is entirely dependent on your specific application.

    Hello Steve,

    What about its lifecycle?

    We have seen that manyTVP5150 parts are NRND, one part is active but its cost is double as compared to others.

    Could you please suggest any recommended part for the new design?

    NRND does not mean the device is obsolete. There are currently no plans to make this device family obsolete.

    NRND simply means that design in support is pretty much limited to my knowledge, and through this forum.
