    There is the NTE864, which is an equivalent IC. But the price for them has gone up to something like $54.

    Futurlec still shows the MAX038CPP available for around $23/ea. Be prepared to pay a hefty shipping charge on top of that, and a wait of at least a month before you get it.

    The output at 20MHz won't be pretty.

    You'd be a lot better off using a crystal oscillator (around $4) in conjunction with a low-pass filter. The low-pass filter could be as simple as a PI filter; a single 820nH inductor with a 160pF cap to ground on either end of it. Choose an Rin and Rt to suit your oscillator.

    using crystall oscilator with lowpass filter is good idea do you have any application for that so i can get idea to implement mine.
