Description
Crystal connection or external reference frequency input. This pin has dual functions. It
can be connected either to an external crystal or an external reference clock.
Crystal connection. If using an external reference, this pin must be left unconnected.
Buffered clock output
3.3V supply
Spread Spectrum Selection
Ground
Buffered clock output
Buffered clock output
Spread Spectrum enable and disable option. When SSON is HIGH, the spread
spectrum is enabled and when LOW, it turns off the spread spectrum.
