Product Details

The ADF4377 is a high performance, ultralow jitter, dual output integer-N phased locked loop (PLL) with 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 ADF4377’s fundamental VCO and output divider 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:

  • automatic reference to output synchronization,
  • extremely well match reference to output delays across process, voltage, and temperature, and
  • sub-ps, jitter free reference to output delay adjustment capability.
  • These features allow for predictable and precise multi-chip clock and 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
