ADF4206/ADF4208 is a dual frequency synthesizer from Analog Devices. It is mainly used in the up-conversion and down-conversion sections of wireless receivers and transmitters. The synthesizer uses a low-noise, digital, phase frequency detector to achieve high-precision and high-stability frequency synthesis.
The ADF4206 and ADF4208 are dual RF PLL frequency synthesizers designed for use in wireless handsets, base stations, and communications test equipment. Each device contains a low noise digital phase frequency detector, a precision charge pump, and programmable counters to implement an N divider. The chips operate with a power supply ranging from 2.7 V to 5.5 V and support a power-down mode to reduce current consumption when not in use.
