XRP6658ISTR-F Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VDD (analog power) first, followed by VCC (digital power), and then the clock signal.
  • Optimize the ADC's performance by adjusting the input impedance, using a low-noise power supply, and ensuring proper PCB layout and grounding. Additionally, consider using a dedicated analog ground plane and decoupling capacitors.
  • The maximum clock frequency is 65 MHz, but it's recommended to operate at 50 MHz or lower to ensure optimal performance and minimize jitter.
  • The XRP6658ISTR-F outputs 8-bit parallel data. You can use a FIFO or a dedicated ADC interface IC to handle the data, or implement a custom interface using an FPGA or ASIC.
  • The typical power consumption is around 120 mW at 65 MSPS, but this can vary depending on the clock frequency, input signal, and operating conditions.
