Yes, the frequency accuracy is not very good. We generated 27MHz out of the CVBS coming from a Philips Directv STB. To do this, just hook up an NXP video decoder to the CVBS/YC signal (such as SAA7111, SAA7114 etc) and that will give you a line-locked 27MHz. Significant medium term drift, measurable on 1/10Hz if I remember correctly. Jumps every so often ( a couple of times per hour) to re-sync. Depends also on the algorithms and PLL inside the STB, different vendor's units all behave differently from what I could see. bye, Said In a message dated 5/9/2008 08:42:08 Pacific Daylight Time, [EMAIL PROTECTED] writes:
Does anyone have experience getting a measurable frequency (in phase with the broadcast FQ) from a consumer DirecTV box? _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. **************Wondering what's for Dinner Tonight?
