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.
