23S08-2HDCGI application field and working principle

23S08-2HDCGI is a high-performance, low-power, low-jitter, fractional-N frequency synthesizer that generates clock signals up to 27 MHz. It operates by modulating the output frequency over a range of 1000 ppm of the center frequency. 23S08-2HDCGI is widely used in various types of communication and industrial applications, such as mobile phones, servers, base stations, wireless communications, storage devices, motor control, etc. It is particularly suitable for applications requiring high frequency precisely.

Working Principle

23S08-2HDCGI uses a digital/analog-hybrid phase-locked loop (PLL) that uses a combination of digital and analog circuits. The PLL first takes in a buffered reference clock, produces a synthesized clock, and offsets it from the reference clock. The frequency for the synthesized clock is determined by the frequency divider ratio of the PLL. The loop filter parameters, along with the fractional-N synthesis, are used to determine the output frequency offset from the reference clock.

The loop filter parameters act to remove jitter on the clock. The fractional-N synthesis uses a look-up table and a digital-to-analog converter (DAC), to obtain a higher level of resolution than normal integer-N synthesis.

In addition, the 23S08-2HDCGI has integrated a programmable start-up sequencer and useful test and diagnostics functions. The start-up sequencer ensures that the PLL automatically goes through multiple states and enters its desired state as quickly as possible. The test and diagnostics functions also report alarms when any problem of loop activity is detected.

Application Fields

23S08-2HDCGI is widely used in various communication and industrial applications, such as mobile phones, servers, base stations, wireless communications, storage devices, and motor control. In mobile phones, it is responsible for generating accurately synchronized frequencies for wireless data and voice transmission. In server applications, it provides a reliable and highly accurate timing source for system bus and memory controllers. In base stations, it provides reliable frequency reference for signal modulations. In storage devices and motor control applications, it provides an accurate frequency reference for data communication.

In motor control applications, 23S08-2HDCGI is an ideal choice, as it provides high precision in controlling motor speed. As a result, it improves the accuracy and speed of motor control in robotics and industrial automation systems. Furthermore, it is suitable for applications requiring frequency synchronization with reference oscillators.

Conclusion

23S08-2HDCGI is a high-performance, low-power, low-jitter, fractional-N frequency synthesizer that generates clock signals up to 27 MHz. Its digital/analog-hybrid PLL, with the fractional-N synthesis, can offset the output frequency from the reference clock over a range of 1000 ppm of the center frequency. Despite its low power consumption, this device also has various useful features, such as a programmable start-up sequencer and test and diagnostics functions, enabling reliable operation in various wireless and industrial applications.
