ADS6422IRGCR datasheet by Texas Instruments

ADS6422IRGCR Frequently Asked Questions (FAQs)

• What is the recommended layout and routing for the ADS6422IRGCR?
  Texas Instruments provides a recommended layout and routing guide in the ADS6422IRGCR Evaluation Module User's Guide (SLAU445). It's essential to follow this guide to ensure optimal performance and minimize noise coupling.
• How do I optimize the clock input for the ADS6422IRGCR?
  The ADS6422IRGCR requires a low-jitter clock input. Use a high-quality clock source, and ensure the clock signal is properly terminated and routed. Additionally, use the clock input capacitor (CCLK) recommended in the datasheet to filter out high-frequency noise.
• What is the maximum input voltage range for the ADS6422IRGCR?
  The ADS6422IRGCR has a maximum input voltage range of ±1.5V, which is not explicitly stated in the datasheet. Exceeding this range may result in reduced performance or damage to the device.
• How do I handle the output data format and alignment for the ADS6422IRGCR?
  The ADS6422IRGCR outputs data in a 14-bit, two's complement format. Ensure that your digital signal processing (DSP) or FPGA is configured to handle this format correctly. Additionally, pay attention to the output data alignment, as it can be configured to be either MSB-first or LSB-first.
• What is the power-down sequence for the ADS6422IRGCR?
  To power down the ADS6422IRGCR, follow this sequence: 1) Set the PDWN pin low, 2) wait for at least 10 clock cycles, and 3) reduce the supply voltage to 0V. This sequence ensures a clean power-down and prevents damage to the device.
