MULTIPHASE OSCILLATOR WITH 40 SPREAD SPECTRUM FREQUENCY MODULATION AND 250KHZ OUTPUT FREQUENCY

MULTIPHASE OSCILLATOR WITH 40% SPREAD SPECTRUM FREQUENCY MODULATION AND 250KHZ OUTPUT FREQUENCY

This is a precision, low power, and easy-to-use oscillator that provides multiphase outputs. The output frequency of the project is set to 250Khz, with 40% spread spectrum. The oscillator frequency can be set by resistor R1, and the spread spectrum can be changed using R3. The master oscillator is controlled by the RSET resistor R1 and has a […]
