I had forgotten about one quite promising candidate -- the THAT300 matched monolithic quad. I have some of those, too. I'll put it on the to-do list. To the best of my knowledge, they do not have reverse protection diodes across the B-E junctions (I've never had any reason to check). Best

Simply pasting the link did not work, but it was close enough :-) The links that include an IP address (like 81.226.54.139 below) only work until midnight EST, then they are cleared. It is easy enough (but not necessarily intuitive) to go to the manuals page and search again for the document.

[time-nuts] Clock stability and its measures

2015-01-29 Thread Attila Kinali
Hi, I have been tasked to give a talk on clock stability and its measures next thursday. Most of the stuff is pretty clear (and the rest can be easily looked up in Rubiolas book, various app notes and papers). But I would like to make sure I did not forget anything important. The types of

Hi Attila, What is your crowd? For telecom or other data-recovery (where the jitter thread is relevant), you may want to also cover MTIE for instance. Also, you want to speak about wander. I'll toss you my slides from my 5 h lecture this Monday. The audience was a bit different, but maybe

You might, depending upon the audience, point out the advantages of heterodyne in the comparison of two RF signals. This, as you know, relieves the burden of precision on the measurement equipment by the heterodyne ratio. Mike -Original Message- From: time-nuts

[time-nuts] Motorola Oncore M12+T Sawtooth

2015-01-29 Thread Tom Wimmenhove
I've built a bunch of carrier board for the M12+T timing receiver. One thing I could not find much information about is the maximum sawtooth (which, I assume, related directly to the frequency of the receiver's internal LO). I know my particular module outputs a correction values between -15 and
