We use the ICS527 for many applications easy to get 80 or 160 MHz. in non critical applications I use an AC14. Have a small board, 14 and ISC only if interested have to look for it it is pre relocation. Juerg may also have one. Corby uses it in his latest HP5065 tests along with a AD9850 DDS.Bert Kehren

How about an ICS525 or ICS527. IDT’s calculator allows a 0 ppm frequency error. You would need a sine-square converter for input.

The main requirement is perfect cycle count accuracy. This is for driving a 16 MHz microcontroller from a 10 MHz Rb/Cs/GPSDO. 10 MHz input is likely sine; 16 MHz output is 3v3 or 5v CMOS.

People have only as much liberty as they have the intelligence to want and the courage to take.
