Working Principle

The XR2206DTR-F works on a fixed frequency range of 0.5 Hz to 1 MHz by using an accurate external resistor and capacitor network. The internal voltage-controlled oscillator (VCO) is contained in the phase-locked loop (PLL), using a fixed offset table to control frequency deviation. The internal linear frequency sweep is completed by switching between Offset Table 1 and Offset Table 2. The upper and lower frequency limits can be adjusted using external capacitor networks. The XR2206DTR-F has an adjustable frequency divider which can provide accurate frequency division of 1 Hz to 8 MHz. It can work with an external crystal for frequency control. The XR2206DTR-F contains a low-noise amplifier and an attenuator, which can adjust the gain and output waveforms.
