Hi all,
Has anyone experimented with the Rakon OCXO unit (STP2777ALF on a small board)
that was on eBay for a while (seller: dasherdeals)? Just now as I was going to
get a link to post, I discovered they have sold out of these units...
I got one this week. There was little information
do :) Of course
you *could* calibrate the sensitivity vector and log all of the arm swings

I have something of a follow up question. How good is the isolation inside
these devices (74LVC, SOT-23 package) between gates?
Let's say I have a 20MHz TCXO. I want to square up the output signal and
divide by two. Easy, just a buffer or inverter and a flip flop. But looking
at the pinout of the
Thanks for all of the replies, very useful. Also for the recommendations on
the 74LVC1G74 and 1G80. I don't know why I didn't check for a 7474 in this
technology, of course they would have that available. But it looks like the
1G80 will do just exactly what I need in a smaller package, so I think
Hi,
Has anyone used or experimented with the 74LVC series of ICs? I have found
them quite useful in projects. Supply voltage of 2-5V, and two inverters or
a single gate or flip flip in a SOT package. They make for much cleaner
layouts than large DIPs.
I'm wondering if they are acceptable
stick with frequency mode. The ADEV plots won't be 100% kosher but they'll
be fine for relative comparisons with other plots from the same measurement
setup.

Hi,
I just picked up an Austron 1210D-03 on eBay. It was an impulse purchase
based on the apparent condition and the fact that it seems like a nice old
clock/reference. I searched for old posts about this unit, found mostly
discussion about the manual and battery pack. Hopefully the price I paid
