Clock Generators, PLLs, Frequency Synthesizers

The SL2309ZC-1 is a programmable digital clock generator and synthesizer device, used for generating precisely timed clock and timing signals for digital systems. The device provides the flexibility of frequency synthesis and clock generation, which can be programmatically configured for diverse system applications. This device is typically used in networking, communications, industrial automation, and other electronic systems requiring high accuracy time-based clocks.

The Application Field

The SL2309ZC-1 is often used in various applications, such as high-speed chip-to-chip communication, storage, and computing systems. It’s a highly versatile, programmable device that can be used to generate different clock and timing signals, such as for serial communication (e.g. Ethernet, USB, PCIe, SATA) and general-purpose clock signals. The device can also be used for frequency synthesis, phase-locked-loop (PLL) synthesizer implementations, and clock jitter attenuation.

Working Principle

At the heart of the SL2309ZC-1 device is a System On Chip (SOC) architecture, which is broken into two main sections: a frequency synthesizer (including a Phase-Locked Loop (PLL)) and a digital clock system. The frequency synthesizer section of the device uses any of the available programmable reference clock inputs to generate a single programmable output frequency. This output frequency is ultimately controlled by a number of internal and external factors, such as the frequency and duty cycle of the reference clock, the device output capability and specified parameters such as fractional frequencies and spread spectrum clock modulation. The digital clock system, meanwhile, is responsible for generating an internally or externally referenced, precisely timed high-speed clock for a variety of applications. This section utilizes an on-chip frequency generator which can operate over a wide range of frequencies, depending on an input reference frequency, input enable signals and device configuration settings. The entire device can be programmed via an I2C compatible data bus. Sophisticated alarms and timing functions can be programmed for each output, allowing for detailed customization and user control. The device also includes a wide range of key features, including frequency synthesis, programmable output frequencies, ultra-low jitter outputs, Spread Spectrum clock modulation and a robust design for high reliability.

Conclusion

The SL2309ZC-1 is a highly flexible, programmable device designed to provide precise timing solutions and meet the needs of various industrial and consumer applications relying on high-speed chip-to-chip communication. The device can generate various clock and timing signals, synthesize frequency, and provide extended features such as PLLs and jitter attenuation. Due to its versatility, the SL2309ZC-1 is an ideal choice for applications in communications, networking, storage, industrial automation, and other electronic systems requiring reliable and high accuracy clock and timing signals.
