Clock/Timing is a special branch of engineering and electronic design that provides the most accurate and reliable timing of events. The CDCR83DBQ is one of the many Application Specific Clock/Timing devices that offers precise timing and circuitry for specific applications. This article will discuss the application field and working principle of the CDCR83DBQ.

Overview of the CDCR83DBQ

The CDCR83DBQ is a Clock/Timing ASIC that is specifically designed for automotive, embedded and industrial applications. It features a robust embedded interface, low power operation and a wide variety of output formats. The device offers dual independent outputs, each of which can be driven independently with configurable frequency, duty cycle and output format.

The device can operate from both a 3.3V and 5V power supply, and the embedded interface allows for easy programming and control of the device. Other features include a programmable frequency range from 32MHz to 3GHz, a configurable drive strength and 7 output formats including LVDS and HCSL.

Application Field of the CDCR83DBQ

The primary application field of the CDCR83DBQ is automotive, embedded and industrial applications. It is commonly used in engine control units, infotainment systems and body electronic systems. In addition, it is also used in applications such as audio systems, satellite systems and GPS navigation systems where precise timing and circuitry are required.

The CDCR83DBQ is particularly well-suited for harsh-environment applications such as in-cabin environment, where the device’s robust embedded interface and flexibility in driving circuit strength and output formats become important. Furthermore, it is also used in applications with high temperature, shock and vibration, as these devices offer long-term reliability.

Working Principle of the CDCR83DBQ

The working principle of the CDCR83DBQ is quite simple. At its core, the device is a frequency divider that takes in a high-frequency clock signal and divides it into two low-frequency signals at different frequencies. The two signals are then used to generate the desired output format, such as LVDS or HCSL, which can then be used by the target application.

The device also features an onboard phase-locked loop (PLL) which can be used to synthesize any frequency between 32MHz and 3GHz. This PLL can be used to generate a single output or can be used to generate multiple frequencies for multiple outputs. The device also features programmable drive strength to ensure that the output signal is properly driven and that noise can be minimized.

Conclusion

The CDCR83DBQ is a versatile and reliable Clock/Timing ASIC specifically designed for automotive, embedded and industrial applications. It offers a robust embedded interface, low power operation and a wide variety of output formats for a variety of timing requirements. The device also features a programmable frequency range from 32MHz to 3GHz, a configurable drive strength and 7 output formats and is well suited for in-cabin environment, high temperature and high shock and vibration applications.
