The FPGA (Field Programmable Gate Array) based digital controller has been implemented for Low level RF voltage control of a 650 MHz cavity. The flexibility of implementing any appropriate control strategy and to have a compact single board solution, FPGA is chosen. The superconducting Cavity is designed to be operated at 650 MHz and 30 kW, CW mode. The voltage from pick-up coil has been fed to the controller after down conversion. The signal is digitized using high speed ADCs. The controller has been tested with different set points and gain parameters from a software connected to the board with serial interface. The FPGA signal processing has been verified according to the required strategy of the reference controller. Some experimental results have been presented for different cavity operational conditions.
