ADS42LB69IRGCT Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate analog ground plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a low-ESR capacitor for decoupling and place it close to the device.
  • Use a low-jitter clock source with a frequency of 640 MHz or higher. Ensure the clock signal has a swing of at least 200 mVpp and a rise/fall time of less than 200 ps. Use a clock buffer or a clock generator with a low jitter output.
  • Use a low-pass filter with a cutoff frequency of 1.5 times the Nyquist frequency to remove high-frequency noise. Use a differential amplifier or a transformer to drive the analog input, and ensure the input signal is within the specified common-mode voltage range.
  • Use a FIFO or a buffer to handle the high-speed digital output data. Ensure the receiving device can handle the data rate of up to 12.5 Gbps. Use a serializer or a deserializer to convert the parallel data to a serial stream if necessary.
  • Power up the analog supply (AVDD) first, followed by the digital supply (DVDD). Ensure the power supplies are stable and within the specified voltage range before applying the clock signal.
