ADCR-E02R7SB105MB - ABRACON

ADCR-E02R7SB105MB Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Abracon recommends a symmetrical PCB layout with a solid ground plane, and keeping the oscillator away from high-frequency noise sources. A 4-layer PCB with a dedicated ground plane is ideal. Refer to Abracon's application note AN-04 for more details.
• How do I ensure the oscillator starts up reliably in my design?
  To ensure reliable startup, Abracon recommends a power-up ramp time of at least 1ms/V, and a power supply voltage that reaches the minimum specified voltage (1.8V) within 10ms. Additionally, decoupling capacitors (e.g., 0.01uF and 0.1uF) should be placed close to the oscillator.
• What is the maximum allowable frequency deviation for this oscillator?
  The ADCR-E02R7SB105MB has a frequency deviation of ±20 ppm over the operating temperature range (-40°C to 85°C). This means the oscillator frequency can deviate by up to ±20 parts per million from the nominal frequency of 10.0 MHz.
• Can I use this oscillator in a harsh environment with high vibration or shock?
  The ADCR-E02R7SB105MB is designed to withstand moderate vibration and shock. However, for harsh environments, Abracon recommends using their more ruggedized oscillators, such as the ADCR-E02R7SB105MB-A, which is designed for high-reliability applications.
• How do I handle ESD protection for this oscillator?
  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. The recommended ESD protection level is ±2kV human body model (HBM) and ±200V machine model (MM).
