Hi all,
I am having a spot of bother with prescaler chips. Basically I need to
find
one at the right price and availability. US$5 each is reasonable, but
where
from? Is there one available that is not obsolete?
I live in Sweden and my local component shop is ELFA (Swedens answer to
RS).
They don't sell ANY digital divider that operates above 50MHz, except for
the 74F163 and I cannot come up with a reliable interface circuit to
couple
an oscillator into it at over 100MHz.
I'd be inclined to use a CPLD. The Xilinx XC9536 would be good to over 150
MHz and a suitable synchronous counter is quite trivial.
73, Leon
