Asking a 100MHz or 1GHz one chip clock generator?

[Fox zhou]

I need a 100MHz or 1GHz high accurate clock as the time base. I hope
it is a one chip solution with low jitter (<10ps). Who knows this kind
of product? Please tell me. Thank you.

This single chip can only be a quartz oscillator.
There are 100MHz Xtal osc available.
10ps rms jitter should be no problem for a quartz based oscillator.
You need -80dBc/rtHz@10Hz, -100dBc/rtHz@1kHz.. -100dBc/rtHz@100kHz

For something else, it is almost unreachable.

In case you'd allow a Quartz plus some other chip there may be more
choices, such as PLL multipliers and so.

I came across a 500MHz quartz-based oscillator a few years ago, and
got a quote for a couple - at about $100 each. The project got canned
before I could order the parts, but the claimed jitter was around
1psec.

If I've read Doug Dwyer's comments correctly, this would have used a
locally thinned quartz crystal as its resonator.

There are some SAW resonators around with higher fundamental
frequencies, but they weren't avaialable in small quantities back when
I was looking.

Thank you. But it seemed that the frequency is lower than 100MHz.

By the way, is that avalible to get a 100MHz CMOS clock generator with 10ps jitter ?
