Counter Dividers Procurement Notes

Verify the specific revision number matches the required datasheet version, as updates may affect electrical characteristics or pinout definitions. Confirm that the PCB layout accounts for the thermal pad requirements of the 40-pin QFN package to ensure proper heat dissipation. Ensure power supply configurations align with the specified voltage levels and termination requirements for optimal performance.

Counter Dividers Selection Notes

Select this component when a wide frequency range up to 24GHz is required with precise integer division capabilities. Consider the CML interface compatibility with existing system logic levels. Evaluate the power supply configuration options, noting that AC termination may be necessary for positive supply setups. Assess the need for dynamic ratio adjustment features versus fixed division requirements.
