HI
Ok, it's TimeNuts, we need numbers…
Say no phase slips is 0.1 UI on the 16 MHz. That would be a jitter number of
6.25 ns RMS.

I think the thread branched and as I recall started something like this.
Someone needed a "Simple" 16 Mhz for a uproc made from a 10 Mhz source.
Two reasonable answers were given.
Injection locked oscillator
Typical div and mult/filter.
A third and kind of interesting for me a Ti chip soic digital
Hi
As I recall the spec was:
1) Cheap
2) no phase slips on the 16 MHz relative to 10 MHz
3) Cheap

How about getting back to basics.
Is it a one off, if production how many and what are the specification
requirements? Otherwise on this list it can go on for a year.

It's actually for an amateur space downlink, Not quite C band but close!
Various mixers are available on the bay from cheep to the not so cheap.
Thanks for the tip regarding the Norsat LNBF. ! I'll let my fingers do
the walking.

If you need that mixer for a LNBF, I believe that is close to the international
C-band. Google around for a Norsat that ends in "I". They use it in India.

If you divide by 5 the phase noise sideband amplitude (voltage) will be
divided by 5.
That is a reduction of 14db for all phase noise sideband frequencies . Then
when you multiply that by 8 you will add the phase noise
sidebands will be multiplied by 8 or 3x6db or 18 db. So the end result will

Daniel,
Another place to go is KE5FX's site. He's got lots of good info on the
stellex ones as well as controlling them with the rf synthesizer that
can be had on that conspicuous auction place.
I've actually purchased several of these with the thought of using
them to drive the LO port of a dbm s
Hi Daniel, I cant remember the reference the web site might help but there
have been at least a couple of articles on YIG modules in VHF Comms magazine

THis is exactly what they are talking about the 74HC390 can do over
50MHz and costs abut 30 cents. You don't need ECL or anything so

this is imperfect enough that there is some fourth harmonic content in

Hello,
Has anyone tried the NV08C-MCM GPS receiver chip?
I’m interested in a chip that will work with all the different satellite
systems.
