Product Overview: ADF4156BRUZ-RL7

The ADF4156BRUZ-RL7 is a high-performance, fractional-N frequency synthesizer from Analog Devices Inc., designed to generate local oscillator (LO) frequencies for wireless applications. This integrated circuit (IC) is part of a family of devices that deliver a combination of high functionality and performance in a compact package, making it ideal for a wide range of communication systems.

Key Features

• Fractional-N Frequency Synthesizer: The ADF4156 allows for fine-tuning of the output frequency, which is essential for modern communication systems that require high spectral purity and fine channel spacing.
• Wide Frequency Range: The device is capable of synthesizing frequencies from 500 MHz to 6.4 GHz when used with an appropriate external VCO (Voltage-Controlled Oscillator), covering most of the frequency bands used in wireless infrastructure.
• High Resolution: It features a 25-bit fixed modulus, and a 13-bit fractional modulus, allowing for high resolution when setting the output frequency.
• Programmable Charge Pump: The ADF4156BRUZ-RL7 includes a programmable charge pump with a current setting range from 0.31 mA to 5 mA, which helps in optimizing the loop filter and VCO performance.
• Low Phase Noise Performance: The synthesizer is designed to exhibit low phase noise, a critical parameter for maintaining signal integrity in communication systems.
• Multiplexed Output: It features a multiplexed readback function for monitoring the N-divider and R-divider values, lock detect, and RF power detector.
• Power Supply: The device operates with a power supply range from 2.7 V to 3.3 V, accommodating various system power requirements.
• Compact Package: Supplied in a compact 16-lead TSSOP (Thin Shrink Small Outline Package), the ADF4156BRUZ-RL7 is suitable for space-constrained applications.
