HMC703LP4ETR

Clock Generators, PLLs, Frequency Synthesizers Overview

The HMC703LP4ETR is an 8 GHz fractional synthesizer in a 24-lead LFCSP package. It supports RF input frequencies from DC to 8 GHz and reference inputs up to 350 MHz. The device operates on 3.3 V analog supplies and 5.0 V charge pump supplies, with current consumption ranging from 3 mA to 95 mA depending on the mode. It features a phase detector rate of up to 100 MHz in fractional mode and delivers a jitter of less than 50 fs RMS. Key performance metrics include a flicker figure of merit of -270 dBc/Hz and a floor figure of merit down to -236 dBc/Hz.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the component matches the specific Analog Devices part number HMC703LP4ETR. Confirm the package type is the 24-lead LFCSP variant. Ensure compatibility with the required supply voltages of 3.3 V and 5.0 V before integration into the design.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when high-frequency synthesis up to 8 GHz is required alongside stringent phase noise specifications. The integrated frequency sweep and external triggering features make it suitable for radar and test applications. Ensure the design accommodates the dual supply requirement of 3.3 V for logic/analog and 5.0 V for the charge pump.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the HMC703 series of fractional synthesizers manufactured by Analog Devices. It shares platform technology with the HMC704LP4E and maintains pin compatibility with the earlier HMC700LP4E PLL, facilitating upgrades within existing designs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The HMC703LP4E is the non-tray version of this component. Verify if the specific ETR suffix is required for tape-and-reel handling or if the standard LP4E package suffices for the assembly process.
