10 or 100mhz.

Try Texas instruments.They have plls.

If 10mhz. the 74hc4046 should be able to perform at that frequency.Or the older CD4046 cmos and the various brands.

Freescale MC145170.

You'll need a micro to configure it. There's pin-programmable versions (MC145151/2) too, though I haven't worked with these.

this is faster but only SOIC, you can use SOIC to DIP adapter.
