55 MHz to 15 GHz, Single-Chip Frequency Synthesizer Offers Low Phase Noise and Spurious Performance

To support a variety of applications such as aerospace and defense, wireless infrastructure, microwave point-to-point links, test and measurement, and satellite terminals, Analog Devices has developed a wideband frequency synthesizer with integrated VCO that provides outstanding performance and flexibility. The ADF5610 uses a fractional-N architecture to generate frequencies from 57 MHz to 14.6 GHz and achieve the lowest phase noise performance of a single-chip frequency synthesizer. Compared to alternative solutions using multiple narrowband, GaAs VCOs and PLLs, the ADF5610 consumes 50% less power, enables smaller size and provides a simpler board design, reducing bill of materials costs and reducing time to market.

Manufactured on ADI’s proprietary SiGe BiCMOS process, the ADF5610 offers +6 dBm RF output power, high system modulation bandwidth, and very low bit error rate. Industry-leading VCO phase noise (−114 dBc/Hz at 100 kHz offset, -165 dBc/Hz at 100 MHz offset at 10 GHz operating frequency) and low normalized phase noise of -232 dBc/Hz end. The integrated PLL enables fast frequency hopping and lock times of less than 30 μs when a suitable loop filter is used. Integer boundary spurs can typically be better than 45 dBc in-band. Levels are typically above the −45 dBc in-band.

Programmable via control software and an integrated SPI interface, the frequency synthesizer is compatible with 1.8 V logic and features hardware and software shutdown modes.

The ADF5610 is biased with separate +3.3 V supplies for the analog, digital, and charge pump circuits, and a +5 V supply for the VCO. The IC is packaged in a 7 mm x 7 mm LFCSP and has an operating temperature range of -40°C to +85°C.

Easy to design and fully supported by ADIsim-PLL™, Analog Devices’ comprehensive, easy-to-use PLL frequency synthesizer design and simulation tool. Using ADIsimPLL, designers can evaluate phase noise, lock time, jitter, and other parameters.
