CDC421125RGERG4 Application Field and Working Principle

Clocking in electronics is an essential process, and effective clock sources are needed to support the accurate synchronisation of signals in any system. In order to meet the increase in the speed, features and power of modern electronic systems, Clock/Timing products such as the CDC421125RGERG4 clock/timing source, a programmable clock/timing generator, are used to provide precisely synchronized timing signals.

The CDC421125RGERG4 clock/timing source is a high performance device with its programmable lock, making it suitable for a variety of applications in the industrial, communications, computer and consumer electronics markets. This device can be used as a clock generator, aPhase Locked Loop (PLL) frequency synthesizer, and/or a Programmable Multi-Frequency Topology (PMFT) frequency synthesizer. It includes both an expansion input/output port and an on-board JTAG debug port, enabling users to optimize their designs specific to each application.

CDC421125RGERG4 Applications

As the CDC421125RGERG4 clock/timing source is a programmable device, a wide range of applications can benefit from its use. It is suitable for industrial applications such as automotive infotainment, heavy-duty audio systems, ATM/POS terminals, robotics, and machine vision. In communications, it is recommended for telecom and datacom systems, radio base stations and switches, as well as Wi-Fi applications. On the computer side, the CDC421125RGERG4 can be used for core logic devices, system clocks, and graphic cards. It is also suitable for various consumer electronic devices such as digital audio systems, picture frames, portable gaming systems, set-top boxes, and digital TVs.

CDC421125RGERG4 Working Principle

The working principle of the CDC421125RGERG4 clock/timing source leverages the use of a phase-locked loop to generate precisely-synchronised clock signals. A phase-locked loop synchronises a reference signal to the input signal and provides outputs at a predetermined frequency that is a multiple of the reference signal (The Tracking principle). In the CDC421125RGERG4, the input signal is picked up by the PLL, amplified, and passed on to the output where the output frequency is determined by the reference clock and the desired frequency output.

The versatility of the CDC421125RGERG4 clock/timing source lies in its ability to support multiple architectures. It offers an array of architectures, such as EEPROM, LVCMOS, HCSL, and LVDS, for interfacing with external devices. The device also features essential features such as holdover enable/disable, power down enable/disable, programmable slew rate, and clock enable control, to suit the requirement of any application.

The CDC421125RGERG4 clock/timing source is a smart choice for applications requiring reliable, precisely-synchronised timing signals. With its wide range of favourable features and versatile architectures, it is no wonder that this device is increasingly becoming the choice of clock/timing source for a growing number of applications.
