    XR2207 VCO by Professor James J. Clark , the page dedicated to this module with full description ,scope shots ,and XR2207 Datasheet : http://www.cim.mcgill.ca/~clark/diy/jjclark_2207_vco.html , the specifications given there :

    Inputs: PWM (pulse width modulation control) 1V/oct (pitch control) LinFM (adjustable AC-coupled linear frequency modulation) ExpFM (adjustable exponential frequency modulation)

    Outputs: Pulse, Triangle, Sawtooth

    Panel Controls: PWM - pulse width modulation amount FINE - fine pitch offset, roughly 1.2 octave range COARSE - coarse pitch offset, roughly 5 octave range LIN FM - linear FM amount Exp FM - exponential FM amount PW - pulse width

    Size - 3U x 12HP (128.5mm x 60.6mm)

    Power Supply Current (max) 35.8mA at +12V, 30.7mA at -12V

    Frequency Range: 15 Hz to 7 KHz Linear Frequency Range (linearity error less than 1%, average 0.13%): 30Hz to 4.2KHz (7+ octaves)
