The oscillator frequency is programmed by a single external resistor (RSET). The frequency-setting resistor can vary from 10kΩ to 2MΩ to select a master oscillator frequency between 100kHz and 20MHz (5V supply). The three-state DIV input determines whether the master clock is divided by 1, 10 or 100 before driving the output, providing three frequency ranges spanning 1kHz to 20MHz (5V supply).
