7Z-38.400MDG-T Frequently Asked Questions (FAQs)

• What is the recommended termination resistance for the 7Z-38.400MDG-T?
  The recommended termination resistance is 1 kΩ, but it's essential to consult the application note or contact TXC Corporation for specific guidance on termination schemes.
• How do I ensure the oscillator starts up reliably in my design?
  To ensure reliable startup, ensure the power supply voltage is stable, and the oscillator is properly decoupled with a 0.01 μF to 0.1 μF capacitor between VCC and GND. Also, verify that the load capacitance is within the recommended range.
• What is the maximum frequency deviation I can expect over temperature and voltage?
  The maximum frequency deviation is typically ±100 ppm over the operating temperature range (-40°C to 85°C) and supply voltage range (1.8 V to 3.3 V). However, this may vary depending on the specific application and environmental conditions.
• Can I use the 7Z-38.400MDG-T in a harsh environment with high humidity and vibration?
  While the 7Z-38.400MDG-T is designed to operate in a variety of environments, it's essential to consult the datasheet and application notes for specific guidance on operating conditions. In harsh environments, consider using additional protection measures, such as conformal coating or hermetic sealing.
• What is the recommended PCB layout and routing for the 7Z-38.400MDG-T?
  To minimize noise and ensure reliable operation, follow good PCB design practices, such as keeping the oscillator signal path short, using a solid ground plane, and avoiding routing critical signals near the oscillator.
