    Hi, I need the register settings for configuring TVP5147 for 10 bit mode and 20 bit mode. If I configure tvp5147 to work in 20 bit mode with discrete sync (reg 33h --> 41h, reg 34h --> 11h), I'm not able to see the data on C lines. but I can see the data on Y lines. can anyone help me by...

    Hi Jim, I'm using TVP5147M1. I am not working in linux. I am working in windows Code Composer studio environment. I am developing CCS diagonostic code for testing TVP5147M1. There is a pull down resistor on pin 69. We are working in 16 bit mode. So, the two LSB's C0 and C1 are not used by...

    Hi Jim, I've solved the problem. The issue is because of board connectivity problem. Also I've verified the status register 3A for C-PLL lock. I thank you so much for your quick response and suggestions. Thanks and Regards Vaishnavi

    Hi, I'm using a TVP5147PFP to capture greyscale square pixel PAL CVBS from a video camera, which on the whole is working. I'm using this with manual gain, as we need computer control of this setting for our application. I've got a really strange problem however, if the video feed is...

    Hello Andrew, I'm really not seeing any significant differences between the two images. The TVP5147 is not recommended for new designs. You really should be using the TVP5147M1. The TVP5147M1 now supports square-pixel mode using patch. See patch download web site below. http://software...

    Hello Jim, Did you view the image at full size? In particular if you look at the innermost black circle, the reflections are visible as lighter arcs. These appear on an otherwise identical image just by disconnecting and reconnecting the video feed. Then while the feed is connected, if I reset the...

    Hello Andrew, OK, I now see the difference at the innermost black circle. Also, the bad image does not appear to have exactly the same overall gain and offset as the good image. The TVP5147 initializes certain registers whenever loss of lock is detected. It may be possible that these registers...

    Hi Jim, Thanks for the suggestions. I've been swamped by some electrical compliance issues the last few days so haven't had a chance to get a unit set up for this test yet. I must admit I don't think I ever tried enabling the autogain to see if it removed the shadowing, although I'm...

    Hi Jim, I've had a chance to test the autogain, unfortunately there's not change seen. I set up a physical switch to switch between autogain, then back to manual gain. With the shadows present, switching to autogain or back again made no difference whatsoever. I did find however that switching...

    Larry, Yes, I2C REG3Ah (Status Register 1) does report that the color subcarrier is in a locked state. We will try with other video sources and let you know. About the crystal: We are using a 100kohm resistor in parallel with the crystal and the load capacitors are both of 33pf. Besides, while...

    Hi All, I am using the TVP5147M1 video decoder with a standard 720x480 NTSC input signal. My question is how do you get both VBLK and VSYNC to output at the same time since the pin on the chip only let you select either function VS or VBLK, not both. I am having to generate the VS signal manually...

    Hi, This issue is blocking us to move further. From VIP parser, we are unable to route the video to the display. So we doubt whether TVP5147 is working fine or not. We've no way other than checking the status registers. Can anyone help us in getting TVP5147 status registers up?? Regards Vaishnavi
