Analog Devices’ Wideband RF Synthesizers
Feature System Size Reduction, Design
Versatility, and Excellent Performance to 13.6 GHz
Analog Devices, Inc. announced the ADF5356, a
13.6 GHz next-generation wideband synthesizer with
integrated voltage-controlled oscillator (VCO) which
targets applications such as wireless infrastructure,
microwave point-to-point links, electronic test and
measurement, and satellite terminals. A complimentary
synthesizer product, the ADF4356, operates to 6.8 GHz
and is comparable in performance.
The ADF5356 generates RF outputs from 53.125 MHz
to 13.6 GHz without any gaps in frequency coverage,
which allows the device to be used as a multiband
synthesizer, thus eliminating the need for multiple
band-specific VCOs/synthesizers products and thereby
reducing component count, board space, and power.
The wideband range is achieved without compromising
performance, since the ADF5356 offers superior PLL
figures of merit (FOM), ultra-low VCO phase noise, very
low integer-boundary and phase-detector spurs, and
high phase-comparison frequency.
Developed on ADI’s proprietary advanced SiGe
BiCMOS process, the ADF5356 and ADF4356 feature
industry leading VCO phase noise (-113 dBc/Hz @ 100
kHz offset at 5 GHz) with integrated rms jitter of just
97 fsec (1 kHz to 20 MHz) and integer-channel noise
floor of -227 dBc/Hz. The phase detector spurious
levels are below -85 dBc typical, and the phase detector
comparison frequency can be as high as 125 MHz.
These RF synthesizers are easy to design-in, and
fully supported by the ADIsimPLL, Analog Devices’
comprehensive and easy to use PLL synthesizer design
and simulation tool for assessing phase noise, lock
time, jitter and other design considerations. To provide
an upgrade path for designers, the synthesizers are pin-
compatible with Analog Devices’ existing ADF5355 and
ADF4355 devices.
The ADF5356 and ADF4356 are specified over the
-40°C to +85°C range. They operate from nominal 3.3-V
analog and digital power supplies as well as 5-V charge-
pump and VCO supplies, and feature 1.8-V logic-level
compatibility.
Analog Devices’ MEMS Accelerometers
Provide Low Power Vibration Measurements,
Enabling Wireless Condition Monitoring
Analog Devices, Inc. (ADI) today announced the
addition of two devices to its popular series of low noise,
low drift, low power, three-axis MEMS accelerometers.
The low noise performance over high frequencies
provided by the new ADXL356 and ADXL357 MEMS
accelerometers delivers high resolution vibration
measurements that enable the early detection of
machine failure in condition monitoring applications. This
performance comes with very low power consumption,
making the ADXL356 and ADXL357 ideal for wireless
sensor networks. These new MEMS accelerometers
are also designed to provide accurate and reliable tilt
measurements for environments high in shock and
vibration without saturating the sensor, an important
requirement for tilt measurement applications on heavy
equipment or airborne platforms such as unmanned
