CDCM1802RGTR is a device that receives an input clock signal. It can also generate multiple output clock signals with the same frequency and phase as the input signal. The output signal can be use to drive multiple circuits or components in the system. Examples include microprocessors, memory chips, or other clock-sensitive devices.

Clock buffers with programmable dividers are a more advanced version of clock buffers. It allows the input clock frequency to be divide to produce an output signal with a lower frequency. The programmable divider can be configuredto divide the input clock by any integer value. Thereby improving the flexibility of system design.

Clock buffers with programmable dividers are commonly used in the following applications. That is require multiple clock signals with different frequencies to drive various components in the system. By taking a single input clock signal and dividing it with a programmable divider. The system can reduce the number of required clock sources. This simplifies system design and reduces costs.
Clock buffers with programmable dividers are commonly used in digital systems. Includes microprocessor, FPGA, and ASIC design. They can also be use in communication systems. Examples include wireless transceivers and networking equipment.
