Wideband PLLs

16 July 2014 Analogue, Mixed Signal, LSI

Analog Devices has rolled out 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 synthesiser, the ADF5355 covers a 55 MHz to 14 GHz frequency spectrum, the widest in its class, while the ADF4355-2 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. Another new member of the family is the ADF4155, an 8 GHz standalone fractional-N PLL.
