Can the ADF7030-1 be used in the range 135 to 175MHz ? or is it restricred to the very narroe 169MHz ISM band ?
The part will operate outside the ETSI 169 MHz band but we have not evaluated the part from 135-175 MHz and it is not included in our production test program. As such we cannot guarantee performance outside the datasheet limits.
Steve, thanks for reply. Just to clarify, does this mean that the onboard M0 processor will accept frequency values between 135 and 175MHz ? (I dont yet have a dev kit to try this). I ask as the PC design tool limits the bottom end frequency to 168MHz. Do you think it likely that future versions will be characterised for wider range operation ?
Hi Tom, yes it will but the PLL will not necessarily lock to the programmed frequency due to the operating range of the VCO - especially over temperature and supply variation. There are no immediate plans to re-characterize the ADF7030-1 so it would take a strong business case.
