TDC1000PW Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VDDA (analog power) first, followed by VDD (digital power) and then the clock signal. This ensures proper initialization of the device.
  • To optimize the timing resolution, ensure that the input signals are clean and have a high signal-to-noise ratio. Also, adjust the gain of the input amplifiers and the threshold voltage of the comparators to optimize the signal-to-noise ratio and minimize jitter.
  • The maximum frequency of the clock signal that can be used with the TDC1000PW is 100 MHz. However, the actual frequency limit may be lower depending on the specific application and the quality of the clock signal.
  • Metastability issues can be handled by using synchronization circuits or by adding additional latency to the clock signal to ensure that the device has sufficient time to settle before making a measurement.
  • To minimize noise and interference, it is recommended to use a multi-layer PCB with a solid ground plane, keep analog and digital signals separate, and use shielding and filtering as necessary. Also, ensure that the device is placed close to the signal sources and that the signal paths are as short as possible.
