The 23S09E-1HPGG8 also provides excellent timing performance, and can be used to generate simple to complex clock frequencies and synchronize multiple devices. It is particularly useful in applications where noise immunity, jitter performance and accuracy are of the utmost importance.

Working Principle

The 23S09E-1HPGG8 is a multi-output clock generator consisting of a Programmable Logic Array (PLA), some configurable logic cells, and a Phase-Locked Loop (PLL). The PLL uses an external reference frequency to measure and close any phase difference between the reference frequency and a divided output frequency, using a phase-frequency detection and control loop.

The 23S09E-1HPGG8 chip is capable of generating up to 8 different frequencies. The user can configure the output frequencies using the PLA, by setting its configurable registers. The user can also use the on-board trimming capability to tune the chip for further performance refinement.

The PLL contains a charge-pump and loop filter to form a current-controlled oscillator. This oscillator generates a synthesized clock frequency on one of the outputs, based on the user-defined required frequency. The output clock can also be divided down to another frequency, and the multiple outputs can be synchronized to each other. The chip also provides a host of other features such as power-down modes, glitch-less operation, low jitter performance, and high accuracy.

Conclusion

The 23S09E-1HPGG8 is a highly versatile and powerful clock generator, making it suitable for a variety of applications. It can be used to generate multiple clock frequencies, with high accuracy and low jitter performance. In addition, it contains a trimming capability for further performance refinement. Therefore, the 23S09E-1HPGG8 is an ideal choice for a wide range of applications such as networking, consumer electronics, industrial automation and control, communications, telemetry, and medical electronics.
