We have a problem with a composite output on one of our products; specifically, the sync structure is defective (the fault is in the silicon). I'm looking for a stand-alone PAL/NTSC sync pulse generator that can be steered by an external V_SYNC or similar. I did think of using an encoder but would like to know if anyone can suggest a more appropriate device.
I believe you can use ADV7391, for timing synchronization purposes, the ADV7390/ADV7391/ADV7392/ADV7393 are able to accept either EAV/SAV time codes embedded in the input pixel data or external synchronization signals provided on the HSYNC and VSYNC pins. It is also possible to output synchronization signals on the HSYNC and VSYNC pins.
For more details refer datasheet.
Thanks Poornima. Now, if you could just solve my email notification problem! Is there a whitelist domain I can use?
I could not understand,Please let us know what does it mean?
No matter what I do, I just cannot get notifications when someone replies to my posts (whjich is why it takes me so long to reply). I'm not the only person to have this problem. I've enabled all the settings as instructed and checked my spam folder but nothing ever gets through and IK have no evidence that the emails are being sent. I would like to add the E-Zone notification server to my whitelist (this is an instruction to my ISP to allow all emails from specific domains), but I don't know the name of the E-Zone domain that sends the emails, because I've never received any!
Even i am also facing the same problem. This problem might occur due to analog server maintenance. Please check with analog IT support team through mail, whether they can assist you.
