Analog Devices Debuts Industry’s Highest Performing 13 GHz PLL Synthesizer
June 18, 2012 Press Release
- Phase detector on the new ADF4159 can operate up to 110 MHz and consumes less than 100 mW; includes high
resolution 25-bit fractional-N modulus and on chip FMCW ramp generation.
Analog Devices, Inc. (ADI) a global leader in high-performance
semiconductors for signal-processing applications, today announced the industry’s highest performance 13 GHz PLL
synthesizer. The ADF4159 achieves breakthrough phase detector operating frequency of 110 MHz and simultaneously
consumes less than 100 mW of power, which is 5 times less than competitive solutions. In addition, the
ADF4159 contains a 25-bit fixed modulus as well as
on-chip functionality to generate highly linear ramp profiles, making it an ideal solution for Frequency Modulated
Continuous Wave (FMCW) radar applications, including automotive radar systems, microwave Point-to-Point (PtP)
systems, communications instrumentation and test equipment.

“Designers of FMCW radar systems, microwave Point-to-Point
communications and test equipment require high frequency solutions that are capable of operating in very high
phase detector frequencies without any sacrifice in power consumption,” said Peter Real, vice president, Linear
and RF Group, Analog Devices, Inc. “As the latest member of ADI’s leading family of PLL synthesizers, the ADF4159
represents an ideal solution for these applications by delivering best-in-class phase-detector frequency of
operation and power consumption.”
Featured in Analog Devices Booth #1725, the ADF4159 Fractional-N PLL
Synthesizer consists of a low-noise digital phase frequency detector (PFD), precision charge pump and a
programmable reference divider. It can be used to implement frequency shift keying (FSK) and phase shift keying
(PSK) modulation. There are also a number of frequency sweep modes available, which generate various waveforms in
the frequency domain, such as sawtooth and triangular waveforms. The ADF4159 features cycle slip reduction
circuitry, which leads to faster lock times, without the need for modification to the loop filter.
ADF4159 PLL Synthesizer Key Features:
Pricing, Availability and Complementary Products
