The document introduces the ADF4113HV high voltage charge pump, which is an integer-N frequency synthesizer with a 15V high voltage charge pump. The synthesizer is designed for use with voltage controlled oscillators (VCOs) that have high tuning voltages (up to 30V).
The ADF4113HV is an integer‑N PLL synthesizer that incorporates a 15 V high‑voltage charge pump, allowing direct drive of VCOs requiring up to 15 V tuning voltage. It operates from a 2.7 V to 5.5 V supply and supports RF input frequencies from 200 MHz to 4 GHz.
The device includes a low‑noise phase‑frequency detector, programmable reference divider, A/B counters, and a dual‑modulus prescaler. Control is performed via a simple 3‑wire serial interface, and the part is pin‑compatible with several earlier ADI PLL families.
