TI does all of their testing: f = 10MHz for the chip - that is in the
datasheet.
If you drive it too hard, expect it to drive too much capacitance, etc -
yeah - the voltage waveform will suffer.
But, using it within the spec - I
Tom,
If you are building your own board - I have used this part:
SN74LVC1G125 - Single Bus Buffer Gate with 3-State Output
and it is suitable for the job. I have measured the performance of the
logic family - and what I observed follows what is in the spec sheets from
TI. I did not
Bob,
Totally agree.
24mA of drive at 3.3V is pretty nice in a small footprint for the parts we
are discussing. Of course as you have pointed out you can drive them at 5V
too.
Mini-circuits is a good place to look too - especially for us hobbyists:

So, I take it no one has looked at these units yet?

Obviously GOOG needs a time-nut on their staff!
Interesting stuff!

Hello All,
I just spoke with JL - I should have one of the Jackson Labs' LC_XO's in my
hands soon (TCXO option) - I was wondering if any of you have had a chance
to look at it - and what your opinion is
of the unit? If you have taken any detailed measurements you would like to

Azelio and Fellow Time Nuts,
Isn't the GPS 1PPS signal supposed to be 'precise' to within what error? I
imagine this is in the specs of the specific receiver -
but I was wondering if some of you have actually measured what that is -
and could report the numbers that you have found.
Thanks!

Hello Everyone,
Thanks for the feedback - I certainly have a lot to think about.
Seems eBay could be a preferred vendor for antennas. I don't need anything
too fancy - but I would like something that does OK in wind and rain, I
don't have to worry too much about snow at my current location -
Hello Everyone,
While we're on the subject - not to get too far off on a tangent - I have
been doing 'web-research' on this - but can someone recommend a great site
or reference for the specifications of the GPS signaling sent down by a GPS
satellite? For instance, I learned that PPS for a

Hello Time Nuts,
I hope this isn't too off topic.
Can I please have some recommendations for a decent active or passive GPS
Antenna to add to the antenna farm that doesn't break the ole' piggy bank?
Thanks In Advance,

Hello David,
Thanks for the pic!
Well, I need something that I can put outside, in the weather, with my
verticals, and other antennas. I am a Ham radio enthusiast, and I want
something I can properly mount and can be an all-weather device and can
live happily 'in the farm' so to speak.

Hello David,
The polar orbiting APT antenna looks interesting.
Thanks again for the pics! And - I know your call sign now too!

Lisa,
Thanks for this update. How many Resolution-T receivers are out there?
Not to go off on another tangent - but I have heard something about 'GPS
jamming during the America's Cup'. Hmmm.
