+The Voltage Controlled Oscillator block is typically used for modulation applications. The block has a control input signal (orange pin) which specifies a frequency. The blue pin generates a sine tone at the appropriate frequency.

+\\ \\
+The input value may be from zero to one (5.23 format, or on ADAU145x/ADAU146x, 8.24 format).
+The VCO accepts values from 0 Hz (0.0 input) to Fs/2 (1.0 input). Fs is the sampling frequency. The algorithm linearly interpolates the input value into an output frequency.
+\\ \\
+Note that if the input is greater than 1, the derived output value will fold back to frequencies below Fs/2.
