I had reached out several times to the new wwvb chip maker for this
timecode.
And though first run chips were available they are not to us unless we want
1000 of them. Also pricing is unclear.
That said yes the intent is to receive time. The new chip doesn't easily
allow a way to d-psk the signal. Though it can be helpful.

Hi

A thousand chips at $1 a chip is a very different thing than a thousand chips at $100 a chip. The next issue might be that they only have them in die form. The issue after that probably is that you really want the version 3 (or 9) chips that actually work with all the modulation schemes. I’ve been down the road with a number of similar chips that took many rev’s before they really did what they were intended to do. Many millions of dollars a pass times 3 or 6 passes is an whole different world …..

These days, though, the "per spin" cost is substantially lower, and the

ASIC spin in CMOS (which works up to low microwave frequencies) is
around $100k and would get you a wafer of dice.

Hi

The price of the spin isn’t just the cost of the masks. There’s a non-trivial cost involved in the redesign of the chip and the testing that finds the problem.

You can indeed do a project run for $5,000 and get usable chips. The same process moved to a single wafer also can give you a few thousand (maybe) of some very expensive dice. If you want a proper mask set and high volume / low cost tooling - it’s not cheap.

Good morning to the group
I do have the extendwave chip sheets. But they are 668K generally in size
so can not send through Time-nuts. I have sent them to Scott already.
