3 V and 5 V power supplies ► 7 mm × 7 mm 48-lead LGA APPLICATIONS ► High performance data converter and MxFE clocking ► Wireless infrastructure (MC-GSM, 5G) ► Test and measurement FUNCTIONAL BLOCK DIAGRAM GENERAL DESCRIPTION The ADF4377 is a high performance, ultralow jitter, dual output 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.
