FOXSDLF/080-20 - Fox

FOXSDLF/080-20 Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the FOXSDLF/080-20?
  The recommended power-up sequence is to apply VCC before enabling the oscillator output. This ensures proper initialization and prevents any potential damage to the device.
• How do I ensure the FOXSDLF/080-20 oscillator is in a stable state during power-up?
  To ensure a stable state during power-up, add a 10nF to 100nF capacitor between the VCC pin and GND. This helps to filter out any noise and ensures a stable power-up sequence.
• What is the maximum frequency deviation of the FOXSDLF/080-20 over the operating temperature range?
  The maximum frequency deviation over the operating temperature range (-40°C to 85°C) is ±100 ppm. This deviation is due to the internal crystal's temperature coefficient.
• Can I use the FOXSDLF/080-20 in a system with multiple power domains?
  Yes, the FOXSDLF/080-20 can be used in systems with multiple power domains. However, ensure that the oscillator is powered from a stable voltage source, and the output is properly isolated from other power domains to prevent noise coupling.
• What is the recommended layout and routing for the FOXSDLF/080-20?
  For optimal performance, keep the oscillator output trace as short as possible, and avoid routing it near noisy signals or power planes. Use a ground plane under the oscillator to reduce electromagnetic interference (EMI).
