SYSTEM DESCRIPTION
The XR-2206 is comprised of four functional blocks; a
voltage-controlled oscillator (VCO), an analog multiplier
and sine-shaper; a unity gain buffer amplifier; and a set of
current switches.
The VCO produces an output frequency proportional to
an input current, which is set by a resistor from the timing

terminals to ground. With two timing pins, two discrete
output frequencies can be independently produced for
FSK generation applications by using the FSK input
control pin. This input controls the current switches which
select one of the timing resistor currents, and routes it to
the VCO.
