Analog Devices' New PLL Synthesizer Facilitates Integration, Flexibility,
Performance and Continuous Frequency Range Support
NORWOOD, Mass.--(BUSINESS WIRE)-- Analog Devices,
Inc. (ADI), a global leader in high-performance signal processing technology and leading provider of RF ICs, today
introduced a PLL (phase-locked loop) synthesizer for wireless communication systems that features the industry’s
best combination of integration, performance, flexibility and the widest continuous frequency-range coverage for a
single RF device. The latest member of ADI’s RF IC product portfolio, the
ADF4351 PLL allows implementation of fractional-N or
integer-N operation continuously over an ultra-wide frequency range of 35 MHz to 4400 MHz while maintaining
excellent phase-noise performance. This has the benefit of allowing customers to greatly reduce the need to
support multiple narrowband synthesizers, thereby reducing inventory and bill of materials costs. The ADF4351
incorporates a high-performance, on-chip VCO (voltage-controlled oscillator) and supports dual output ports, which
allows the part to have unsurpassed flexibility and performance in a small surface-mount package.

The ADF4351 PLL features programmable
divide-by-1/2/4/8/16/32/64 circuits, which allow the user to generate an RF output frequency anywhere between 35
MHz and 4400 MHz. This means that engineers no longer have to design multiple synthesizers for different bands,
which speeds design cycle times and reduces component costs. For applications that require isolation, the RF
output stage can be muted. The mute function is both pin- and software-controllable. Furthermore, control of all
of the on-chip registers is through a simple 3-wire interface. The ADF4351 PLL operates with a power supply
ranging from 3.0 V to 3.6 V and can be powered down when not in use.
ADF4351 PLL with Integrated
VCO; Key Features:
- Leading RF performance: rms jitter of 0.3 ps typ; typical EVM of 0.4% at 2.1 GHz
- Ultimate Flexibility: programmable dual-modulus prescaler of 4/5 or 8/9; programmable output power level,
dual output ports, integer-N or fractional-N operation
- Analog and digital lock detect
- Switched bandwidth fast-lock mode
- Cycle slip reduction
Pricing, Availability and Complementary Products
The ADF4351 PLL can be incorporated readily into circuits for wireless communications applications and is
well-suited to operate with other ADI RF ICs, including the ADL5801 RF mixer, ADL5375 modulator and ADL5382
demodulator.
