LTC2387CUH-18#PBF Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the LTC2387?
  A good PCB layout for the LTC2387 involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the analog signal traces. A 4-layer PCB with a dedicated analog ground plane is recommended.
• How do I ensure accurate clock jitter performance with the LTC2387?
  To ensure accurate clock jitter performance, use a high-quality clock source, keep the clock signal traces short and shielded, and avoid running digital signals near the clock signal traces. Also, use a clock frequency that is within the recommended range of 10MHz to 100MHz.
• What is the recommended power-up sequence for the LTC2387?
  The recommended power-up sequence for the LTC2387 is to first apply the analog supply voltage (AVCC), followed by the digital supply voltage (DVCC), and then the clock signal. This ensures that the analog circuitry is powered up before the digital circuitry.
• How do I optimize the performance of the LTC2387 in a noisy environment?
  To optimize the performance of the LTC2387 in a noisy environment, use a low-pass filter on the analog input signals, use a shielded enclosure, and keep the analog signal traces away from digital signal traces. Also, consider using a ferrite bead or a common-mode choke on the power supply lines.
• What is the maximum operating temperature range for the LTC2387?
  The maximum operating temperature range for the LTC2387 is -40°C to 125°C. However, the device's performance may degrade at temperatures above 85°C, so it's recommended to operate the device within the -40°C to 85°C range for optimal performance.
