ARJM21A1-547-AB-EW2 Frequently Asked Questions (FAQs)

  • Abracon recommends a land pattern with a pad size of 1.3mm x 0.8mm, with a non-solder mask defined (NSMD) pad shape, and a minimum clearance of 0.2mm between the pad and the solder mask.
  • To ensure reliable startup, Abracon recommends a power-on reset (POR) circuit, a decoupling capacitor of 10nF to 100nF between VCC and GND, and a series resistor of 1kΩ to 10kΩ between the oscillator output and the MCU input.
  • The ARJM21A1-547-AB-EW2 is rated for operation from -40°C to +85°C, but Abracon recommends derating the frequency tolerance by 0.05ppm/°C for temperatures above 70°C.
  • Yes, the ARJM21A1-547-AB-EW2 is compatible with 3.3V supply voltage, but Abracon recommends ensuring the oscillator output voltage is within the MCU's input voltage range to prevent damage or malfunction.
  • Abracon recommends implementing ESD protection measures, such as TVS diodes or ESD protection arrays, on the oscillator input and output pins to prevent damage from electrostatic discharge.
