The CDC924DLRG4 Clock/Timing-Application Specific chip is a programmable bit-precision static differential frequency divider that is used for a variety of applications including frequency synthesis, hybrid clock synthesis, frequency division, frequency scaling, and time division multiplexing.

The CDC924DLRG4 contains two low power CMOS frequency dividers that share a common clock. The desired output frequencies are easily programmed via a serial interface. The programmable output frequencies range from 1 to 1/SSM (substroke multiple) of the input frequency, where SSM is programmable from 1 to 38 and represents the number of input pulses required to produce one output pulse. The CDC924DLRG4 also incorporates a programmable duty cycle output shift register that permits duty cycle adjustments to be made with a single command. This shift register is enabled/disabled through the serial interface.

The CDC924DLRG4 is ideal for applications where different output frequency requirements need to be met. It provides flexibility to generate frequencies which are multiples of the input frequency. This can be used to generate clock signals for various applications such as 1.2GHz Java personal digital assistants and cellular phones. This chip can also be used for producing clock signals for high-speed chip-to-chip communications.

The working principle of the CDC924DLRG4 chip is fairly simple. It takes an input clock signal, typically of an invariable frequency, and divides it according to the programmed output frequencies. Since the output frequency signal is derived from the input clock signal, it is possible to achieve a wide range of output signaling frequencies, ranging from 0zero to the maximum allowed frequency.

The output clocks produced by the CDC924DLRG4 can also be programmed for any required phase shift. This is especially useful for clock deskewing and clock synchronizations, where different clock sources need to be aligned in phase. In addition, the CDC924DLRG4 also comes with programmable drive strength, allowing the flexibility to adapt to different output requirements.

The CDC924DLRG4 can be used in a variety of applications that require different output clock frequencies. It can be used to generate clocks for communication, radio, television and navigation systems, as well as in digital image processing systems and medical and serological imaging.

In addition, the CDC924DLRG4 also provides a flexible architecture that can be used to generate custom timing signals. It is possible to program different ratios between the input and output frequencies which can be used to generate higher frequency clocks for digital signal processing applications. The CDC924DLRG4 is ideal for applications requiring high speed and precision, such as in the automotive, aerospace and industrial sectors.

The CDC924DLRG4 offer flexibility and performance for a wide range of clock and timing applications. With its easy programming capability and its high frequency output clocks, the CDC924DLRG4 can provide a reliable frequency division of the input signal, making it a great choice for Clock/Timing - Application Specific applications.
