Hello all,
I have a nice 32MHz 3.3V CMOS 50% duty cycle clock, and I'd like a /2
and a /1 copy with less than +/-1ns skew between rising edges. Of
course I can stick the clock into a 74vhc74 strapped as a /2, but how
do I get a buffered copy with the same tpd and low skew? Is there a
way to find an inverter or a buffer in the other flip flop in the 74
package?
My brain is kind of burnt right now (flu + overwork), do you think if
I use tinylogic parts, 1 flip flop and 1 buffer, I can get a tpd and
skew matched to each other across a 5% variation in supply and 10C to
50C temp range, even though it's two chips?
I just wanna know real quick so I can order parts on Digikey for the
weekend, hopefully by then I'll be able to read datasheets again
thanks!
