I'm building a SWRX with PLL frequency generator and need a 1/2 dozen
of these chips. They are unobtanium from my Vancouver suppliers.

I need the speed of AS or S because the master osc. will be 60-90 MHz.

I'd use a CPLD - it'll be faster, cheaper and take up less board space.
You can use it for the rest of the logic as well, including the phase
detector.

Hi Leon,

Thanks. But as a tubehead myself, how on earth do I go about doing this?
