AN-1009 GreenPAK Macro Circuit Design: Voltage Controlled Oscillator with External RC Circuit
The GreenPAK2 chip has an internal RC Oscillator (RC OSC), with a set of configurable frequencies in the range of 29.11 kHz – 8.43 MHz. But in very special cases the user might have a need for the clocking source that has a different frequency from those available on the RC OSC. For this purpose, the user can create an RC based oscillator using external resistance and capacitance together with GreenPAK internal circuits.
