HMC832A Fractional-N PLL with Integrated VCO 25 MHz to 3000 MHz

The HMC832A is a 3.3 V, high performance, wideband, fractional-N, phase-locked loop (PLL) that features an integrated voltage controlled oscillator (VCO) with a fundamental frequency of 1500 MHz to 3000 MHz and an integrated VCO output divider (divide by 1, 2, 4, 6, … 62) that enables the HMC832A to generate continuous frequencies from 25 MHz to 3000 MHz. The integrated phase detector (PD) and Σ-Δ modulator, capable of operating at up to 100 MHz, permit wider loop bandwidths and faster frequency tuning with excellent spectral performance.

Industry leading phase noise and spurious performance, across all frequencies, enable the HMC832A to minimize blocker effects, and to improve receiver sensitivity and transmitter spectral purity. A low noise floor (−160 dBc/Hz) eliminates any contribution to modulator/mixer noise floor in transmitter applications.

The HMC832A is footprint compatible to the market leading HMC830 PLL with an integrated VCO. It features 3.3 V supply and an innovative programmable performance technology that enables the HMC832A to tailor current consumption and corresponding noise floor performance to individual applications by selecting either a low current consumption mode or a high performance mode for an improved noise floor performance.

Additional features of the HMC832A include 12 dB of RF output gain control in 1 dB steps; an output mute function to automatically mute the output during frequency changes when the device is not locked; selectable output return loss; programmable differential or single-ended outputs, with the ability to select either output in single-ended mode; and a Σ-Δ modulator exact frequency mode that enables users to generate output frequencies with 0 Hz frequency error; and a register configurable 3.3 V or 1.8 V serial port interface (SPI).
