integer-N phased locked loop (PLL) with an integrated voltage controlled oscillator (VCO) ideally suited for data converter and mixed signal front end (MxFE) clock applications. The high performance PLL has a figure of merit of −239 dBc/Hz, ultralow 1/f noise, and a high phase frequency detector (PFD) frequency that can achieve ultralow in-band noise and integrated jitter. The fundamental VCO and output divider of the ADF4377 generate frequencies from 800 MHz to 12.8 GHz. The ADF4377 integrates all necessary power supply bypass capacitors, saving board space on compact boards.
For multiple data converter and MxFE clock applications, the ADF4377 simplifies clock alignment and calibration routines required with other clock solutions by implementing the automatic reference to output synchronization feature, the matched reference to output delays across process, voltage, and temperature feature, and the less than ±0.1 ps, jitter free reference to output delay adjustment capability feature.
These features allow for predictable and precise multichip clock and system reference (SYSREF) alignment. JESD204B and JESD204C Subclass 1 solutions are supported by pairing the ADF4377 with an integrated circuit (IC) that distributes pairs of reference and SYSREF signals.

Evaluation Kits (1)
The EV-ADF4377SD1Z evaluates the performance of the ADF4377 frequency synthesizer with an integrated voltage controlled oscillator (VCO) for phase-locked loops (PLLs). A photograph of the EV-ADF4377SD1Z is shown in Figure 1 of the user guide. The EV-ADF4377SD1Z contains the ADF4377 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 are ac-coupled with 50 Ω transmission lines making the outputs suitable to drive 50 Ω impedance instruments. The EV-ADF4377SD1Z requires an SDP-S board (not supplied with the kit). The SDP-S allows software programming of the EV-ADF4377SD1Z with ACE software. Full specifications for the ADF4377 frequency synthesizer are available in the ADF4377 data sheet, which must be consulted with the user guide when working with the EV-ADF4377SD1Z.
