Texas Instruments recommends a symmetrical layout, with the device placed near the center of the board, and using a solid ground plane to reduce noise. Additionally, use short, direct traces for clock signals, and avoid crossing clock signals with other signals.
Use a series termination resistor (Rs) of 50-75 ohms, and a parallel termination capacitor (Cp) of 1-2 pF, placed close to the output pin. This will help match the impedance and reduce signal reflection.
The maximum frequency deviation for the input clock signal is ±100 ppm. If the input clock signal deviates beyond this range, it may affect the output clock signal's frequency, phase, and jitter performance.
The CDCLVD1212RHAR can tolerate input clock signal duty cycle distortion up to 45/55%. However, excessive distortion may affect the output clock signal's duty cycle, and may require additional conditioning or correction.
Use a 10-22 uF decoupling capacitor, placed close to the power pin, and a 1-10 uF filter capacitor, placed between the power pin and ground. This will help reduce power supply noise and jitter.
