    I don't think you will found a 160M crystal, but it's relatively easy to find a 160M oscillator.
    I have also 3 CY22150KFC and 3 CY22393FXC (cypress programmable clock synthesizers) that I will try when up with laboratory again.

    Another part can be TI CDCE913/25/37/49: I had good experiences in the past with 25 and 49 models.
