LMK61E2-156M25SIAT Frequently Asked Questions (FAQs)

  • A good PCB layout for the LMK61E2-156M25SIAT involves keeping the oscillator circuitry away from noisy signals, using a solid ground plane, and minimizing trace lengths and vias. TI provides a recommended layout in the datasheet and application notes.
  • To ensure reliable startup, make sure the power supply is stable and within the recommended voltage range. Also, ensure the oscillator output is not loaded excessively, and the output is not short-circuited during startup.
  • The LMK61E2-156M25SIAT has a specified frequency deviation of ±25 ppm over the operating temperature range of -40°C to 85°C. This means the frequency can vary by up to ±156 Hz (25 ppm of 156.25 MHz) over the entire temperature range.
  • The LMK61E2-156M25SIAT is not specifically designed or tested for radiation-hardened applications. For such applications, TI recommends using oscillators specifically designed and qualified for radiation-hardened environments.
  • To troubleshoot issues with the oscillator not oscillating, check the power supply voltage, ensure the oscillator output is not loaded excessively, and verify the PCB layout is correct. Also, check for any shorts or opens on the oscillator circuitry.
