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 the CDCE925PW 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, use the device's built-in jitter filtering capabilities and adjust the loop bandwidth to optimize jitter performance.
The CDCE925PW can operate up to 2.5 GHz, but the maximum frequency range depends on the specific application and the quality of the input clock signal. Consult the datasheet and application notes for more information.
To configure the CDCE925PW for SSC, set the SSC_EN pin high, and adjust the SSC frequency and modulation rate using the SSC_FREQ and SSC_MOD pins. Consult the datasheet and application notes for more information on SSC configuration and optimization.
To ensure optimal performance, follow good PCB design practices, such as using a solid ground plane, minimizing signal trace lengths, and using shielded cables for clock signals. Consult the datasheet and application notes for more information on layout and routing guidelines.
