ADF4351 | Arduino Library for the ADF4351 Wideband Frequency

ADF4351 is a C++ library. ADF4351 has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

This library supports the ADF4351 from Analog Devices on Arduinos. The chip is a wideband (34.375 MHz to 4.4 GHz) Phase-Locked Loop (PLL) and Voltage Controlled Oscillator (VCO), covering a very wide frequency range under digital control. Just add an external PLL loop filter, Reference frequency source and a power supply for a very useful frequency generator for applications as a Local Oscillator or Sweep Generator. The chip generates the frequency using a programmable Fractional-N and Integer-N Phase-Locked Loop (PLL) and Voltage Controlled Oscillator (VCO) with an external loop filter and frequency reference. The chip is controlled by a SPI interface, which is controlled by a microcontroller such as the Arduino. The library provides an SPI control interface for the ADF4351, and also provides functions to calculate and set the frequency, which greatly simplifies the integration of this chip into a design. The calculations are done using the excellent Big Number Arduino Library by Nick Gammon. The library also exposes all of the PLL variables, such as FRAC, Mod and INT, so they examined as needed. Requires the BitFieldManipulation library: Requires the BeyondByte library: A low phase noise stable oscillator is required for this module. Typically, an Ovenized Crystal Oscillator (OCXO) in the 10 MHz to 100 MHz range is used.
