ADF4106BRU

The ADF4106BRU from Analog Devices is a high-performance PLL frequency synthesizer IC with a 6.0 GHz bandwidth. It operates within a power supply range of 2.7V to 3.3V, making it suitable for various wireless communication systems.

This device integrates a low-noise digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider, and programmable A and B counters, along with a dual-modulus prescaler. The architecture allows for the implementation of local oscillators in both up-conversion and down-conversion sections of wireless receivers and transmitters. Its high bandwidth capability can eliminate the need for frequency doublers in many high-frequency systems, simplifying design and reducing costs.

The ADF4106BRU is available in a 16-TSSOP surface-mount package. It operates over a temperature range of -40°C to 85°C. Key features include programmable prescalers, programmable charge pump currents, and programmable antibacklash pulse width, along with analog and digital lock detect capabilities. It also supports hardware and software power-down modes.

Applications for the ADF4106BRU include broadband wireless access, satellite systems, instrumentation, wireless LANs, and base stations for wireless radios. The device utilizes a 3-wire serial interface for programming and control.
