ADRF6620-What type of crystal oscillator signal(ex. Sine wave, clipped sine wave, LVCMOS, HVCMOS,,,,etc) should be inputted to REFIN in ADRF6620?

ADRF6620-What type of crystal oscillator signal(ex. Sine wave, clipped sine wave, LVCMOS, HVCMOS,,,,etc) should be inputted to REFIN port of PLL in ADRF6620?

While I was searching for crystal oscillators, there are many different oscillators with different output signals.

Most general one found is LVCMOS. However, it is square wave signal.

For ADRF6620, what type of oscillator signal should be inputted to REFIN port of ADRF6620.

NOTE: REFIN is synthesizer reference frequency input.

  • Hi yoonjoki,

    The customer evaluation board of the ADRF6620 employs a TCXO (IT2200A from Rakon) which can be used as a reference point in your search for a reference source. You can use OCXO, TXCO or VCXOs for that matter, assuming the frequency and output power level is within the specifications. I would advise you to try out reference sources with the customer evaluation board. Please let me know if this helps.
