Overview
The ADF4113HVBCPZ-RL7 is an integer-N frequency synthesizer produced by Analog Devices Inc. This device is designed 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, a programmable reference divider, programmable A and B counters, and a dual-modulus prescaler (P/P + 1). 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. It is particularly useful in applications requiring high voltage VCOs, such as IF/RF local oscillator (LO) generation in base stations and point-to-point radio systems.
