HMC833LP6GETR

Clock Generators, PLLs, Frequency Synthesizers Overview

The HMC833LP6GETR is a fractional-N phase-locked loop (PLL) with an integrated voltage-controlled oscillator (VCO), manufactured by Analog Devices Inc. It generates frequencies from 25 MHz to 6000 MHz using a fundamental VCO range of 1500 MHz to 3000 MHz, supported by an integrated divider and doubler. The device features a maximum phase detector rate of 100 MHz and delivers ultra-low phase noise of -110 dBc/Hz typical in-band, with a figure of merit (FOM) of -227 dBc/Hz. RMS jitter is less than 180 fs. It operates on 3.3 V supplies for digital/analog logic and 5 V for the charge pump and VCO core, housed in a 40-lead 6x6 mm LFCSP package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct channels. Confirm the presence of the H833 marking and lot number on the package. Ensure handling procedures comply with ESD sensitivity Class 1B ratings. Check for RoHS compliance documentation as specified in the datasheet. Validate that the supply chain source provides valid traceability records for this specific part number.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the HMC833LP6GETR when wide bandwidth coverage from 25 MHz to 6 GHz is required with low phase noise. Consider the 100 MHz max phase detector rate for loop filter design flexibility. Ensure power supply requirements match the 3.3 V and 5 V rails specified. Evaluate thermal management needs given the 9 °C/W junction-to-ground paddle thermal resistance. Verify compatibility with existing serial control interfaces (SEN, SDI, SCK).

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Hittite Microwave Corporation portfolio, now part of Analog Devices Inc. It is designed as a high-performance frequency synthesizer replacing discrete PLL/VCO solutions. The LP6 suffix indicates the leadless plastic package type. The GETR suffix denotes tape and reel packaging for surface mount assembly. It serves as a key building block for RF front-end modules requiring precise frequency generation.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult Analog Devices application support for potential cross-references or newer generations within the same product family. Ensure any replacement maintains compatible pinout, voltage levels, and control interface protocols.
