Analog Devices has released a wideband synthesizer with integrated voltage-controlled oscillator (VCO) and phase-locked loop (PLL) that delivers “breakthrough” performance and flexibility and is ideal for diverse market applications such as aerospace and defense, wireless infrastructure, microwave point-to-point links, electronic test and measurement and satellite terminals.
ADI’s ADF5610 wideband fractional-N synthesizer generates RF outputs from 55 MHz to 15 GHz and provides the industry’s lowest phase noise performance for a single IC. Compared to alternative solutions that require multiple narrowband GaAs VCOs and phase-locked loops (PLL), the ADF5610 offers 50 percent less power dissipation and a smaller footprint with a simpler architecture, which translates into bill of materials cost savings and reduced time-to-market. Developed on ADI's proprietary advanced SiGe BiCMOS process, the ADF5610 enables high modulation bandwidths and low bit error rates.
It's integrated VCO achieves phase noise of −114 dBc/Hz at 100 kHz offset and −165 dBc/Hz at 100 MHz offset, both at 10 GHz, and a normalized phase noise floor (FOM) of −229 dBc/Hz. The integrated PLL provides fast frequency hopping and lock times less than 50 μs with the appropriate loop filter. Phase detector spurious levels are below −45 dBc typical, and the RF output power level is 6 dBm.
The ADF5610 wideband fractional-N synthesizer is 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 parameters. The device is also customer programmable through the use of integrated SPI interface and control software.
The ADF5610 is specified over −40°C to +85°C. It operates from nominal 3.3 V analog and digital power supplies, as well as 5 V charge-pump and VCO supplies and is compatible with 1.8 V logic. The synthesizer also contains hardware and software power down modes.
