5. Electrical parameters are guaranteed by design with these operating conditions, unless otherwise noted.
6. External input reference clock must have a duty cycle between 40% and 60%, measured at V
7. Please refer to application note “Crystal Oscillator Topics” for information on AC-coupling the external input reference clock.
8. The oscillator circuit is optimized for a crystal reference and for external reference clocks up to 20 MHz. For external reference clocks above 20 MHz, it is recommended
9. Xtal inputs have CMOS thresholds.
