Errata: For information on silicon errata, see “Errata” on page 49. Details include trigger conditions, devices affected, and proposed workaround.
Notes
1. Errata: The worst case IMO frequency deviation when operated below 0 °C and above +70 °C and within the upper and lower datasheet temperature range is ±5%.
2. Errata:The I
