SA602A oscillator
 

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

Yes I did, but, what about it? i think it does not give much
information for components to be used for the oscillator

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.
