THS9000DRWT datasheet by Texas Instruments

THS9000DRWT Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the THS9000DRWT?
  A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output traces short and away from each other to minimize crosstalk.
• How do I ensure the THS9000DRWT is properly biased for optimal linearity?
  Use a voltage regulator to provide a stable supply voltage, and ensure the input common-mode voltage is within the recommended range (0.5V to 2.5V). Also, use a low-ESR capacitor for decoupling.
• What is the maximum input signal amplitude that can be applied to the THS9000DRWT?
  The maximum input signal amplitude is 2.5Vpp differential, but it's recommended to limit it to 2Vpp to ensure optimal linearity and minimize distortion.
• How do I filter out noise and aliasing in the output of the THS9000DRWT?
  Use a low-pass filter with a cutoff frequency below the Nyquist frequency (half the sampling rate) to filter out noise and aliasing. A 3rd-order Butterworth filter is a good starting point.
• What is the recommended clock frequency for the THS9000DRWT?
  The recommended clock frequency is between 10MHz to 100MHz, but it can operate up to 200MHz. Ensure the clock signal is clean and has minimal jitter for optimal performance.
