Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers
CDC421A312RGET application field and working principle
The CDC421A312RGET is an integrated circuit used as a clock generator. It is a product of Texas Instruments and is the industry’s most compact and power-efficient clock generator solution. This device integrates a clock generator, phase-locked loop (PLL), and power management components, thus it helps reduce power consumption, board space, and cost. With a high-resolution PLL, the device offers superior performance, optimal flexibility, and rack-mountable solutions.
The device is targeted at network infrastructure and enterprise applications as well as consumer applications. It has application in fields such as telecommunications, enterprise storage, broadcast TV, and consumer electronics such as displays, cameras, and media players. The device also provides solutions for Internet of Things (IoT) applications. In such applications, it helps reduce system power and cost by replacing multiple discrete components.
The CDC421A312RGET is an integrated clock generator with a frequency synthesizer and PLL. It combines the frequency synthesizer and PLL components together in a single package to reduce board space and cost. The PLL provides precise timing synchronization, while the frequency synthesizer provides precise signal frequency tuning. The clock generator also offers a low-current standby mode and a low-power shutdown mode. This helps to reduce overall system power consumption.
The CDC421A312RGET features an output clock frequency range from 2 Hz to 150 MHz, a low-phase-noise synthesizer, a low-jitter PLL, and a low-power shutdown mode. It has programmable modulus dividers and low-skew outputs for fan-out options. The device’s programmable power-down mode provides the flexibility to power down different blocks during idle event, in order to reduce system power consumption. The device offers flexible internal frequency select options and wide output range to support multiple applications.
In addition, the device has a built-in core regulator, making it a complete power management solution. The regulator provides a low-power standby mode for the device, thus increasing its efficiency. The device also provides voltage difference detection (VDD) feature to prevent the device from entering a low-power mode when the supply voltage is not stable.
The CDC421A312RGET is equipped with a range of features to ensure stability and reliability. The device has a temperature monitor that compares a diode voltage to a reference to monitor the health of the device, and also has a brown-out detect and reset circuit that resets the device when it encounters power failure. It also offers a watchdog timer to detect and respond to occurrences of system malfunction.
The device is backed by a strong quality assurance system, ensuring it provides industry-leading performance and reliability. The device is RoHS compliant and supplied in a 7 mm×6 mm quad flat no-lead (QFN) package. The device offers a wide temperature range for operation and storage, making it ideal for a wide range of application environments.
In summary, the CDC421A312RGET is a versatile clock generator solution designed for use in a wide range of consumer and enterprise applications. It combines a frequency synthesizer, phase-locked loop, and power management components into a single package and helps reduce power consumption, board space, and cost. The device provides a range of features to ensure stability and reliability, making it a cost-effective choice.
