fast logic

Hi,

Does anybody make fast logic gates/flops (multi-GHz rates, 50 ps edges, ecl or cml) besides On and Micrel? Not EL or EP, that's too slow.

Interesting that Micrel (Sy55 series) and On (NBSG series) have a few similar parts, but the On parts are at least twice the price. A single NBSG53 flipflop is close to $40. It's annoying to design logic at $40 per gate.

Maybe some GaAs from Oki, Sony, Triquint, but probably not much more than what they need for their fiber links and at outragous prices.

There is a fast comparator from AD with 35 ps risetime that might be interesting.

National/TI seem to have this & that.

For me, it's currently Micrel & On.

We use the ADCMP582, and it's nice, even if only to generate edges. But I need to do some downstream logic that will transmit, say, a 100 ps pulse.

I did just discover On's NB7V series, which is similar to the NBSG stuff but half the price.

Hittite will sell you gates and flops for somewhere north of $100 per.
