Richardson RFPD Announces New Fractional-N Wideband Synthesizer With Integrated VCO From Analog Devices

ADF4368 can be synchronized to support multiple frequency conversions systems

Richardson RFPD, Inc., an Arrow Electronics company, announced today the availability and full design support capabilities for a new microwave wideband synthesizer from Analog Devices, Inc.

The ADF4368 is a high-performance, ultra-low jitter, integer-N and fractional-N phase-locked loop with integrated VCO. It is ideally suited for frequency conversion applications.

The high performance PLL has a figure of merit of −239 dBc/Hz, very low 1/f noise of normalized −287 dBc/Hz and high PFD frequency that can achieve ultra-low in-band noise and integrated jitter. The ADF4368 can generate any frequency from 800 MHz to 12.8 GHz without an internal doubler, eliminating the need for sub-harmonic filters. The Σ-Δ modulator includes a 25-bit fixed modulus that allows hertz frequency resolution and an additional 17-bit variable modulus, which allows even finer resolution and flexibility for frequency planning. It requires DC supplies of 3.3 V and 5 V.

The ADF4368 eases development time with a simplified serial-peripheral interface register map, external SYNC input, and repeatable multichip phase alignment in integer mode and fractional mode. It has a jitter of less than 30 fs and a noise floor of -160 dBc/Hz (at 12.8 GHz). The synthesizer uses the SYNC input or EZSync software programming to support multiple frequency conversions systems, such as MIMO or phased array applications.
