ADF4208 Datasheet (Analog Devices) - Dual RF PLL Frequency Synthesizers

ADF4208, Dual RF PLL Frequency Synthesizers

The ADF420x family of dual frequency synthesizers are used to implement local oscillators in the upconversion and downconversion sections of wireless receivers and transmitters.

Each synthesizer consists of a low noise, digital, phase frequency detector (PFD); a precision charge pump; a programmable
