CDCE949QPWRQ1 Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VDD, and then the input clock signal. This ensures proper device operation and prevents potential latch-up conditions.
  • To optimize for low jitter performance, ensure that the input clock signal has a high signal-to-noise ratio, use a low-jitter clock source, and minimize the number of clock domain crossings. Additionally, optimize the PCB layout to reduce noise and ensure proper decoupling.
  • The maximum frequency of operation for the CDCE949QPWRQ1 is 200 MHz. However, the actual operating frequency may be limited by the specific application and system requirements.
  • The CDCE949QPWRQ1 can be configured for a specific output frequency by programming the device's internal registers using the I2C interface. The specific configuration will depend on the desired output frequency and the input clock frequency.
  • The typical power consumption of the CDCE949QPWRQ1 is around 30-40 mA, depending on the operating frequency and output configuration. However, the actual power consumption may vary depending on the specific application and system requirements.
