Xr2206 Schaltung. From this forum i came to know that xr2206 is used to produce a sample sinusoidal signal whose frequency can be varied with the voltage at pin1. Monolithic function generator xr 2206 the xr 2206 is a monolithic function generator integrated circuit capable of producing high quality sine square triangle ramp and pulse waveforms of high stability and accuracy.
1hz 2mhz xr2206 function generator produces high quality sine square and triangle waveforms of high stability and accuracy. And can be adjusted by vr3. Output of 1hz 2mhz xr2206 function generator can be connected directly to 60mhz counter for setting precise frequency output.
Anyways in the datasheet i observed frequency shift keying fsk.
1 is the use of the 5k pot connected to sv5. 60mhz frequency meter counter measures frequency from 10hz to 60mhz with 10hz resolution. S 1 open for triangle closed for sine wave. Xr2206 function generator kit includes output that can be directly connected to 60mhz counter kit for measuring and displaying output frequency on lcd display.
