The ADF4382 is a high performance, ultra-low jitter, fractional-N phased-locked loop (PLL) with an integrated voltage controlled oscillator (VCO) ideally suited for local oscillator (LO) generation for 5G applications or data converter clock applications. The high performance PLL has a figure of merit of −239 dBc/Hz, low 1/f noise and high PFD frequency of 625 MHz in integer mode that can achieve ultra-low in-band noise and integrated jitter. The ADF4382 can generate frequencies in a fundamental octave range of 11 GHz to 22 GHz, thereby eliminating the need for subharmonic filters. The output dividers on the ADF4382 allow a complete output frequency range to be generated from 687.5 MHz to 22 GHz.

For multiple data converter clock applications, the ADF4382 automatically aligns its output to the input reference edge by including the output divider in the PLL feedback loop. For applications that require deterministic delay or delay adjustment capability, a programmable reference to output delay with <1 ps resolution is provided. The reference to output delay matching across multiple devices and over temperature allows predictable and precise multichip alignment.

The simplicity of the ADF4382 block diagram eases development time with a simplified serial peripheral interface (SPI) register map, external SYNC input, and repeatable multichip alignment in both integer and fractional mode.

Product Details

The EV-ADF4382SD1Z evaluates the performance of the ADF4382 frequency synthesizer with an integrated voltage-controlled oscillator (VCO) for phase-locked loops (PLLs). A photograph of the evaluation board is shown in Figure 1 in user guide. The EV-ADF4382SD1Z contains the ADF4382 frequency synthesizer with an integrated VCO, a USB interface, power supply connectors, on-board reference oscillator, propagation delay calibration paths, and Subminiature Version A (SMA) connectors. The outputs of the EV-ADF4382SD1Z are AC-coupled with 50 Ω transmission lines, making these outputs suitable to drive 50 Ω impedance instruments.

The EV-ADF4382SD1Z requires an SDP-S controller board, which is not supplied with the evaluation board kit). The SDP-S allows software programming of the EV-ADF4382SD1Z with Analog Devices, Inc., ACE software.

Full specifications for the ADF4382 frequency synthesizer are available in the ADF4382 data sheet, which must be consulted in conjunction with this user guide when working with the EVADF4382SD1Z.
