Overview
The ADF4113HVBCPZ is an integer-N frequency synthesizer produced by Analog Devices Inc. This device is specifically designed for use with voltage-controlled oscillators (VCOs) that have high tuning voltages, up to 15 V. It features a high voltage charge pump, a low noise digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider, and programmable A and B counters. The synthesizer operates with a power supply ranging from 2.7 V to 5.5 V and includes a dual-modulus prescaler (P/P + 1) and a simple 3-wire interface for controlling all on-chip registers.
