The SA602 oscillator ir primarily intended for fundamental mode crystals.
Your 32 mhz crystal is probably a 3rd overtone unit. It will probably
require a tuned circuit to ensure that it comes up on the third overtone and
not on the fundamental frequency. I recall that the Philips app note shows
how to do that.

Hi every one!

I'm currently working on a project using SA602A with a 32MHz crystal
oscillator. The crystal is specifed with 30 pF load capacitance. I'm
not able to make the crytal works. I use 120p and 40p in series, for
the crystal.And I follow the circuit given in SA602A data sheet for
cellular radio application. Can anybody help me with this one,
please..Thanks

Have you read page 4-3?
