Re: End of "The Telephone Flea Market"

Shows how drunk I used to get when I visited Dallas for a weekend! I was convinced it started Friday night.

<google> Ah it did, but was still called 'first saturday'. that explains it :)

That was mentioned as not fitted yet. Experiments to follow I believe.

I meant to ask as I got in some 2068DD in readiness before you finally decided on the 5532. I assume the differences are small enough as to be not a worry in use?

Holy cow, you are an animal! I think that may be the fastest turn around I've ever seen. Nice work!
I would take longer to place the mouser order! But I think this is proof of the 'meaure twice cut once' approach. I'm still impressed how close the breadboard was to the finished board.

The BUF634 is dead, long live the BUF634A

I am really unsure which large customer persuaded them to port a 20 year old design onto their latest 36V SiGe process but there we go. If you need a 200MHz buffer here you are :)

Re: entropy continued?

Sounds a good plan. Something isn't right there and you need this unit to be reliable to earn you money :)

Re: entropy continued?

There is a right tool for the job. Worth having if you stick a log of ICs into sockets.
