Overview
The ADF4113HVBRUZ-RL7 from Analog Devices Inc. is an integer-N frequency synthesizer designed for applications requiring high voltage charge pumps and precise frequency control. This device is particularly suited for use with voltage-controlled oscillators (VCOs) that have high tuning voltages, up to 15 V. It features a low noise digital phase frequency detector (PFD), a precision high voltage charge pump, programmable reference and N dividers, and a dual-modulus prescaler. The synthesizer operates with a power supply ranging from 2.7 V to 5.5 V and includes a power-down mode for energy efficiency.
