Description
Crystal connection or External reference clock input.
Crystal connection. If using an external reference, this pin should be left open.
Spread Spectrum ON/OFF. Spread Spectrum function enabled when HIGH, disabled when
LOW. Has an internal pull--up resistor.
Ground
Modulated clock output
Modulation Rate Select. When LOW selects Low Modulation Rate. Selects High Modulation
Rate when pulled HIGH. Has an internal pull--up resistor.
Analog Deviation Selection through external resistor to GND.
