Overview
The HMC4069LP4E is an Integer-N synthesizer produced by Analog Devices Inc. This device integrates a 10 to 1300MHz digital phase-frequency detector and a 10 to 2900MHz 5-bit frequency counter, making it ideal for low phase noise synthesizer applications. It is designed to operate in conjunction with a differential loop amplifier to phase lock a Voltage-Controlled Oscillator (VCO) to a reference oscillator. The HMC4069LP4E is packaged in a 24-pin, 4 x 4mm leadless QFN surface mount package with an exposed ground paddle for enhanced RF and thermal performance.
