PCK3807ADS,112 Application Field and Working Principle

The PCK3807ADS,112 is a clock buffer, driver and divider module designed by the PCK chip. This clock buffer is especially unique in its ability to buffer an input clock in order to ensure the highest accuracy and lowest jitter. It is a great choice for applications like PLLs, crystal oscillators and embedded systems.

Application Fields

The PCK3807ADS,112 can be used in a variety of applications and provides many benefits. The device is designed for frequency synthesizers, FIFOs, Asynchronous FIFOs, PLLs, phase-locked loops, crystal oscillators, phase-locked delays, DC-DC converters, microcontrollers, and embedded applications.The device has the ability to buffer an input clock to ensure that the output clock has the highest accuracy and lowest jitter. The ultra-fast startup time of the device makes it ideal for embedded applications that require fast initialization times. Additionally, the device can also divide and spread the input clock, giving even more flexibility and options to the user.

Working Principle

The PCK3807ADS,112 utilizes a unique working principle that makes it especially suitable for many applications. It is essentially used as a clock buffer and driver. The device first receives an input clock, which is then buffered and amplified to deliver a high output signal. This output signal is then further spread and divided, providing great accuracy and noise immunity.The internal architecture of the PCK3807ADS,112 is very complicated and rather unique. It features two propagation delay chains, which essentially act as a PLL buffer. The first chain consists of six stages that delay the input clock by 15ps per stage. The second chain is used to delay the output clock, with each stage providing a delay of 30ps per stage.The output clock is further divided but the PCK3807ADS,112 ensures that the jitter is kept to a minimum. It features two output dividers, with the first providing a divide ratio of 1, 2, 4, 8 or 16. The second output divider provides a divide ratio of 16, 32, 64, 128 or 256.

Conclusion

The PCK3807ADS,112 is a clock buffer, driver, and divider module designed by the PCK chip. It has the ability to buffer an input clock in order to ensure the highest accuracy and lowest jitter. It is ideal for frequency synthesizers, FIFOs, Asynchronous FIFOs, PLLs, phase-locked loops, crystal oscillators, phase-locked delays, DC-DC converters, microcontrollers, and embedded applications. The device has two propagation delay chains, and two output dividers, which provide even more flexibility and options to the user. With its unique working principle and ability to spread and divide, the PCK3807ADS,112 is a great choice for many applications.
