Is there any IC chip designed to be a Crystal Oscillator

[abs]

There are a lot of LC Oscillator Chip,(like mc12149).but is there any IC for Crystal Oscillator??? I want build an low phase noise Oscillator.
If there any one can help.

I seem to remember a lot of crystal oscillator modules were based on an IC from someone like JVC or maybe JRC but I don't know the part number.

Here are just a few examples from various manufactures:

SiLabs Crystal Oscillators

I've used XOs from both these manufactures, they each have their pros and cons.

Hope this helps you in your endeavor.

Cypress Clock Generation - Programmable Clocks - Programmable Crystal Oscillator (XO) - Serial Configurable - Spread Spectrum Clocks - Cypress Semiconductor

Thank you,but I means, The output of the Oscillator,must be "Pure" SIN wave, Not square wave for Digital Clock .
the harmonic must be "very" low.
