ACHL-8.192MHZ-ER - ABRACON

ACHL-8.192MHZ-ER Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the ACHL-8.192MHZ-ER crystal oscillator?
  Abracon recommends a layout with a ground plane underneath the oscillator, and keeping the traces as short as possible to minimize noise and radiation. A 4-layer PCB with a dedicated ground layer is ideal.
• How do I ensure the ACHL-8.192MHZ-ER oscillator starts up reliably in my design?
  To ensure reliable startup, Abracon recommends applying a power-on reset to the oscillator, and using a capacitor with a value between 10nF to 100nF between the VCC and GND pins to filter out noise.
• What is the maximum operating temperature range for the ACHL-8.192MHZ-ER crystal oscillator?
  The ACHL-8.192MHZ-ER has an operating temperature range of -40°C to +85°C, but it's recommended to derate the frequency tolerance by ±0.05ppm/°C for temperatures above +70°C.
• Can I use the ACHL-8.192MHZ-ER oscillator in a design that requires a specific frequency accuracy?
  Yes, the ACHL-8.192MHZ-ER has a frequency accuracy of ±20ppm, but Abracon offers custom frequency options with tighter tolerances (e.g., ±10ppm or ±5ppm) upon request.
• How do I handle ESD protection for the ACHL-8.192MHZ-ER oscillator in my design?
  Abracon recommends using ESD protection devices, such as TVS diodes or ESD arrays, on the oscillator's input and output pins to prevent damage from electrostatic discharge.
