TVP7002EVM Questions

This question is not answered

Hello,

The customer is having some issues with the TVP7002EVM kit.  He using an input of 1280 x 768 @60Hz and setting the output to run @ 1080p.  His video output looks redish and is constantly scrolling up.  The settings he is using are:

 

System Initialization

 

(TVP7002 - Switch to EVM VGA Input)

(1280x768x60Hz- 47.8khz - 79.5MHz HS/VSin -/+)

(CSC Bypass)

 

for the TVP7002 Property Sheet he used the preset settings

for the THS8200 Property Sheet he is not sure what to set the HS_IN_delay and VS_IN delay to.

Thank you,

Alex

    Alex,

    The EVM cannot convert from a 1280 x 768 @60Hz input to 1080p output.  When the 1280x768 WinVCC dataset is selected and used to program the TVP7002 and THS8200, the TVP7002 and THS8200 will both be configured for 1280x768.  A scaler ICwould be required to convert between formats.

    How does the customer plan to use the TVP and/or THS in their design?

    I want to have as a input to the tvp2002-> VGA running @  (1280 x 720) or (1176 x 664)   with a refresh rate of 60Hz

    and as a output from the ths8200 I want 720p

    I also want to have as a input  vga (1280 x 768) @ 60Hz resolution and a output of 720p also

    I wanted to have as a input (1280 x 720) VGA and have the kit convert this to 720p component video.  The preset resolutions that the kit comes with does not have a setting for (1280 x 720) but is has a setting for (1280 x 768).  So I downloaded the tvp7002_ths8200_evm_kit_081811.CMD file from TI and use the settings for the 720p for the THS8200 to output.  Next I used the settings for 1280 x 768 for the TVP7002.  I had to adjust the feed back divider so that the total pixels that were sent to the HHS8200 were under 1650 so it would fit in the 720p active window.  And I got the picture to come up,  I also had to uncheck the RGB out and Bypass CSC to get the proper color.  So this is what I have  going now

    Input -> 1280 x 720 (vga) @60Hz

    output -> 720p (Y Cr Cb) @60Hz

    TVP7002 + THS8200 720p60 RGB toYPbPr 422 Embedded Syncs 12-15-11.cmd

    Kati,

    There is 1280x720p VESA RGB format that has timing that is identical to 720p component.  This format can be supported with the EVM kit using the attached CMD file.  This CMD file uses a 4:2:2 embedded sync interface between the TVP7002 and THS8200.  The TVP7002 converts RGB to YCbCr and the THS8200 outputs YPbPr component.  Both devices are set to the 1280x720p timing.

    The 1280x768 RGB format has different timing (pixel rate, line rate ) than 720p, so the output will not be true 720p.

    Is there a way to do this so I have no data loss, as in use 0 - 1023 output code range and 4:4:4  format for 1280 x 720

    Hi Larry Taylor

    i have sum problem on the TVP7002 and DM365 card

    i input from ch3 to the TVP7002 RGB 1280/702 60h

    i run the encoder demo .

    the encoder stak and look is no buf get into .

    can u send my instruction how to .

    Thanks .doron sandroy

    Here are settings that we have used for 720p60 RGB to 20-bit 4:2:2 YCbCr with embedded syncs.   This setup is for use with an external 27MHz REFCLK connected to Pin80 of the TVP7002.  If this external REFCLK is not present, you will need to select internal REFCK in I2C REG1Ah.  It is possible that your issue is related to the DM365 frame capture startup.  Try starting or reseting frame capture after the TVP7002 has been programmed and after a 720p source has been connected.
