Hi,
I would like to know the allowable frequency deviation in the operating frequency range of ADF7242 in 0 deg and 50 deg temperatures..

Hi,
Look into datasheet: "Frequency Error Tolerance"
Klaus
I believe it's a senseless question. Frequency tolerance of the generated signal depends exclusively on the initial accuracy, temperature drift and aging of the utilized crystal or reference oscillator. Allowed frequency variation is commanded by the application and in part by regulations like ETSI or FCC.
Thanks for the replies. If I can put it in this way, I am actually looking for the frequency stability of the 26 MHz crystal oscillator used.
Crystals with down to +/- 10 ppm stability over temperature range are available from several vendors. For better stability use external temperature compensated oscillator (TXCO).
