TVP5150: TVP5150

Part Number: TVP5150

Hi,

I am currently working on a module that includes analog video decoder to decode the NTSC video signal on the input side and outputs the decoded data in CPI format. TVP5150 seems to be a better fit to do this, but while  searching for its evaluation board TVP5150EVM online, I could see that it is obsolete. So I just thought of doing the development board for TVP5150 from my end, but I wanted to check what are the required components that needs to go on a self developed board inorder to test the TVP5150 functionality effectively. Also I could see that the video registers on the obsolete board is initialized using I2C serial interface and the board also includes the WinVCC4 application program for the system operation. 

Is there any way that I can get the WinVCC4 application program online so that I can use it to test the TVP5150 decoder after interfacing it with the self developed board. Kindly clarify me on the evaluation board specifications that are required to effectively test the functionality of TVP5150. Also please let me know whether I can get the WinVCC4 application program even though the evaluation board TVP5150EVM is obsolete and is not available in any online electronic store.

Thanks in advance!

    Unfortunately the WinVCC application was written for a very specific parallel port interface and USB to I2C converter, so would not work for your custom board.

    For your custom board I would suggest a circuit very similar to the application diagram in the datasheet, then use an external I2C interface like either an Aardvark or a Bus Pirate to send I2C commands to the TVP5150.

    Referring to the application diagram...

    SW1 is not required.
    AAF = Anti-alias filter. Not really needed for basic testing. This is an image quality control and will depend on your video source quality.
    IO_DVDD should be set to 3.3V.

    From a programming perspective all you should need to do after power up is enable the clock and data outputs, all the other defaults should be fine for ITU656 output format.

    BR,
