The CDC421250RGETG4 is an enterprise-grade system-on-chip (SoC) solution designed for the demands of next-generation clock and timing generators. It is a PLL based device that works on different technologies like TRI-STATE, SYNC and register transfer logic (RTL). It leverages a new interval awareness technology, PSN, that lets users establish faster, more reliable, and more accurate clock and timing generators.

The CDC421250RGETG4 is designed to simultaneously provide up to eight frequency outputs. It offers superior accuracy, ranging from 0.01ppm to 138ppm (+/-10-300kHz) depending on the chip grade and frequency. The CDC421250RGETG4 makes use of a unique combination of logic and memory cells to enable a wide variety of clock frequencies, offsets and intervals to be generated, programmed and updated with minimum latency.

Using CDC421250RGETG4 helps reduce the complexity of determining the timing requirements of systems, allowing developers to focus more on their application functions instead of the timing accuracy of their systems. This makes it well-suited for applications such as network switches, routers, storage controllers, modems, processors, and digital signal processors.

The CDC421250RGETG4 works in two phases. First, the chip initializes the clock frequency and offset, then tests and corrects the offset and frequency drift in the second phase. It also allows various parameters to be programmed, such as output frequency offsets, phase shift, duty cycle and phase noise. Data is exchanged between the chip’s control module and external user devices, as well as its internal FPGA registers, making it suitable for a wide range of timing applications.

The CDC421250RGETG4 also features an integrated Package-on-Package (PoP) function to increase its versatility. This includes the capability to internally couple multiple chip pins to external user pins, allowing the user to integrate additional functions and features such as ADC and DAC. This allows the chip to support a variety of application demands.

The CDC421250RGETG4 is ideal for applications that require highly accurate, low power, and highly reliable timing. It utilizes a variety of new technologies and clock generators for the purpose of providing users with the highest level of performance, accuracy and stability.

In summary, the CDC421250RGETG4 is considered a clock/timing device specialized in clock generators, PLLs, and frequency synthesizers. With its range of features and technologies, this SoC solution is capable of meeting the needs of different types of applications, allowing developers to create highly reliable and accurate clocks while minimizing complexity.
