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.

APPLICATIONS

  • High performance data converter and MxFE clocking
  • Wireless infrastructure (MC-GSM, 5G)
  • Test and measurement

    Product Details

    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.

    Product Details

    This dual AD9213 evaluation board is a wideband direct RF sampling 20GSPS digitizer platform which includes the two 12bit 10 GSPS RF ADCs. The RFADCs are time interleaved by 180 degrees, thus supporting a 20 GSPS sampling system. Synchronization performance is obtained to within 1 sample accuracy using the built-in multichip synchronization capabilities. The clock input interleaving is achieved by using the ADF4377, which is a low jitter microwave wideband synthesizer with an integrated VCO. This dual AD9213 reference design platform provides a path to scale up the bandwidth of interest or be used to enable end user algorithm development.
