someone explain to me why they use the programmable oscillator and how used that what's her advantages !

 

Hello,

For wich frequency range will the oscillator be used?
A programmable oscillator will need control hardware to set the frequency.

Bertus

 

Most oscillators consume more power the faster they run, so choosing a low frequency, where appropriate, can be used to conserve power. This is a particular concern with battery-powered circuits.

Bertus

frequency range is betwen 100MHZ and 160 MHZ.
we used varcator to control th frequency

 

Hello,

Then you could have a look at the Si570 from Silicon Labs.
There is a development kit available at their site:

I have a variable frequency oscillator between 100 and 150 MHz I have to display the frequency by a dsp processor like stm32 or TMS320 ..., someone help me to choose a dsp processor or ADSP

 

Basically you have to build a freq counter, and therefore counters have to
be able to cout at a rate of 150 Mhz max. "Normally" this has been done
in the past using a fixed prescaler and subsequent low speed counters in the
counter chain.

Today one can get fast counters in FPGA technology.

Something like this (1 channel, ignore other 3 channels) -

This sounds like homework. Is it?
