DSC1033CI1-002.0480 Frequently Asked Questions (FAQs)

• What is the recommended crystal oscillator circuit configuration?
  The recommended crystal oscillator circuit configuration is a series resonant circuit with a 10pF to 22pF load capacitance on each side of the crystal, as shown in the Microchip application note AN954: 'Crystal Oscillator Basics and Crystal Selection for Microchip Devices'.
• How do I ensure accurate clock frequency calibration?
  To ensure accurate clock frequency calibration, use the internal oscillator calibration mechanism, which is described in the device's datasheet. This mechanism allows the device to adjust its internal oscillator frequency based on an external reference clock.
• What is the maximum allowed clock frequency deviation?
  The maximum allowed clock frequency deviation is ±100 ppm over the entire operating temperature range, as specified in the device's datasheet.
• Can I use an external clock source instead of the internal oscillator?
  Yes, you can use an external clock source instead of the internal oscillator. The device has a dedicated external clock input pin that can be used to drive the clock signal from an external source.
• How do I handle clock switching between internal and external clock sources?
  To handle clock switching between internal and external clock sources, use the clock switching mechanism described in the device's datasheet. This mechanism ensures a smooth transition between clock sources without disrupting the device's operation.
