HMC832LP6GE

Clock Generators, PLLs, Frequency Synthesizers Overview

The HMC832LP6GE is a fractional-N phase-locked loop (PLL) with an integrated voltage-controlled oscillator (VCO), manufactured by Analog Devices Inc. It operates within a frequency range of 25 MHz to 3000 MHz and requires a single 3.3 V supply. The device features a maximum phase detector rate of 100 MHz, enabling wide loop bandwidths and fast frequency hopping. Typical in-band phase noise is −110 dBc/Hz, with a fractional figure of merit (FOM) of −226 dBc/Hz. It includes a programmable performance technology allowing selection between low current consumption and high performance modes. The component is housed in a 40-lead QFN package measuring 6 mm × 6 mm.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Confirm that the required RoHS compliance status matches the version available from authorized distributors. Check for any active product discontinuance notifications or end-of-life statuses prior to finalizing procurement plans.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the HMC832LP6GE when a wide tuning range up to 3 GHz is required with minimal external components. Choose the low current mode for power-sensitive applications and high performance mode for superior noise floor requirements. Ensure the reference input frequency does not exceed 350 MHz and verify that the charge pump current settings align with the desired loop filter design for optimal settling time.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The HMC832 is part of the HMC83x series of wideband fractional-N PLLs with integrated VCOs. It serves as a footprint-compatible successor to the HMC830, offering improved power efficiency through its programmable performance technology while maintaining similar physical dimensions and pinout configurations for easy board upgrades.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The HMC830LP6GE is a compatible alternative within the same family, though it lacks the programmable performance technology found in the HMC832. Verify that the target application can accommodate the slight differences in current consumption and noise performance characteristics between these two models.
