    So I have a few of these crystal oscillators salvaged, Vp900479, marked up as 106.25 mhz oscillators, I have other f req's too.
    I'm having trouble getting data for it, even a pinout, dove electronics supply them but there website isnt any use data wise.
    I dont really even know if these are xo's, vcxo's or even tcxo's.
    Any idea's on pinout?, I might just try one connected the same way as a standard 14 pin dil oscillator module and see if it works or blows up.

    Hi Debe, no its an smd not a standard brick package:
    http://www.gsdz-ic.com/stock/detail/vf900479-106.250mhz.html
    I did find in the end that the pinout is the same as the standard brick, only pin 1 is output enable.
    Some of the Vf900 modules say they are a oven controlled module, no idea if mine are or not, valpey dont seem to want folks getting data for them.
    I have a few of these, if you put a tuned dipole direct on the o/p they go a surprising distance, they'd make a easy little beacon.

    For anyone looking for pinouts on these modules, they are the same as the pic above.

    Or:

    1 output enable, active high
    2 deck
    3 clock o/p
    4 3.3 / 5v juice
