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.
