HMC4069LP4E 2.9 GHz Integer-N Synthesizer
The HMC4069LP4E from Analog Devices is a high-performance Integer-N frequency synthesizer designed for low phase noise applications. It integrates a 10 to 1300 MHz digital phase-frequency detector (PFD) and a 10 to 2900 MHz 5-bit frequency counter, enabling programmable division ratios from N = 2 to 32. The device operates from a 4.75 V to 5.25 V supply and supports an operating temperature range of -40°C to 85°C.
The HMC4069LP4E delivers ultra-low single-sideband (SSB) phase noise of -151 dBc/Hz at 10 kHz offset with a 100 MHz reference/VCO input at +5 dBm, making it well-suited for high-performance synthesizers with wide loop bandwidth and fast switching. It includes integrated output resistors and improved input sensitivity to simplify loop filter design and enhance signal integrity. The device supports CMOS/TTL-compatible logic inputs and provides lock detect and invert functionality for robust system monitoring and control. When used with a differential loop amplifier, it generates output voltages to phase-lock a voltage-controlled oscillator (VCO) to a reference source, enabling stable and low-noise frequency synthesis up to 2.9 GHz.
