New PLLs Deliver Wide Frequency Range Coverage and Low VCO Phase Noise
Analog Devices (Tampa, FL) 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. Key features include:
- ADF5355: 55 MHz to 14 GHz synthesizer with integrated ultra-low-noise VCO.
- ADF4355-2: 55 MHz to 4.4 GHz synthesizer with integrated ultra-low-noise VCO.
- ADF4155: 8 GHz stand-alone fractional-N PLL.
