New PLLs Deliver Widest Frequency Range Coverage and Lowest VCO Phase Noise in a Single Device

PLLs cover frequencies from 55 MHz to 14 GHz
and deliver breakthrough noise performance for macro-cell base
stations, point-to-point systems, radar, and test and measurement
applications.
INTERNATIONAL MICROWAVE SYMPOSIUM -- Analog Devices, Inc.
(NASDAQ: ADI) introduced today three new phase-locked loop (PLL)
devices one of which features the industry’s widest frequency
coverage and lowest voltage-controlled oscillator (VCO) phase noise
in a single device. Targeted at RF and microwave communications
systems designers who need a single, high-performance wideband
synthesizer, the ADF5355 PLL covers a 55 MHz to 14 GHz frequency
spectrum, the widest in its class, while the ADF4355-2 PLL features
a 55 MHz to 4.4 GHz frequency span. Both PLLs integrate
ultra-low-phase-noise VCOs that deliver -133 dBc/Hz @ 1 MHz offset
at 6 GHz—at least 2 dB lower noise performance than any competing
device.
ADI today also introduced the ADF4155, an 8 GHz stand-alone
fractional-N PLL. Together, the new devices provide designers with
several options for replacing discrete, high-frequency,
higher-power PLLs and VCOs in demanding, ultra-wideband
applications including cellular base stations, microwave
point-to-point communications links, radar systems and test and
measurement equipment. These new PLLs are all supported on the
latest version of the ADIsimPLL™ design tool, version 3.6, which is
a free-to-download software tool that facilitates PLL/synthesizer
designers in getting the best performance from ADI’s leading
portfolio of PLL solutions. The new PLL synthesizers and ADIsimPLL
tool will be demonstrated this week at Analog Devices’ Booth
#415.

The superior VCO phase-noise performance of the ADF5355 and
ADF4355-2 is achieved through novel VCO topologies and
architectures which were developed in conjunction with ADI’s new
proprietary advanced SiGe processes. In ultra-wideband RF and
microwave communications applications, this ultra-low phase noise
has the benefit of improving overall system error rates and
increasing data throughput to deliver better noise immunity and
wider range.
ADI’s new, cost-effective, ultra-wideband PLL synthesizer ICs
also feature up to 125 MHz phase comparator frequency and 38-bit
resolution, which lowers jitter and allows for very fine step
sizes, while the integrated PLL and VCO on an advanced BiCMOS
process significantly reduces package size and power consumption
compared to discrete GaAs implementations. And because a single PLL
can be configured to operate from 55 MHz to 14 GHz, designers can
more quickly reconfigure their system designs and reduce their
parts inventory while still supporting multiple frequency
bands.
