Working Principles

The LTC6900IS5#TRMPBF is a programmable oscillator IC that generates precise frequencies based on the input provided through the FREQ pin. It utilizes an internal resistor network and a current source to generate a voltage-controlled current. This current is then fed into an integrator, which produces a linearly increasing or decreasing voltage ramp. The frequency of the output waveform is determined by the rate at which the voltage ramp reaches certain thresholds. By adjusting the input frequency, the LTC6900IS5#TRMPBF can generate a wide range of frequencies.
