ADF4251 General Description

The ADF4251 is a dual fractional-N/integer-N frequency synthesizer that can be used to implement local oscillators (LO) in the upconversion and downconversion sections of wireless receivers and transmitters. Both the RF and IF synthesizers consist of a low noise digital PFD (phase frequency detecto.
