[time-nuts] 5 Mhz to 10 Mhz and 25 Mhz

[millerke6f at aol.com]

You might look at the NB3N502  PLL mult chip. I've used this chip on my rubidium interface board and other projects.  It's cheap, current production and does a number of multipliers from 2X 2.5X 3X 3.333333x 4X and 5X  Available from Mouser and others.  I'm using one in a hybrid CW transmitter as a nearly coil-less scheme with a 6CL6 final.  all 5 bands from either a 80 meter or 40 meter crystal. Keys really clean too.

Bert was looking at the ICS512 and have to agree the price is cheap. How
have you applied them. It seems really simple. Do you follow with
filtering. Looking at 5 > 10 MHz and 5 > 15...
