2308B-1DCGI8 is a high performance Clock Generator, Frequency Synthesizer, and Phase-Locked Loop (PLL) in a single butterfly package. It is designed to provide a cost-effective solution for applications requiring a wide range of frequencies, from single-output frequencies to multi-output multiplexing applications. The device is capable of generating frequencies up to 600MHz with low phase noise and clean, high-performance clock edges.

Application Fields

The 2308B-1DCGI8 is suitable for a wide variety of applications ranging from testing and measurement instruments to networking and communications equipment. It is specifically designed for those applications where multiple frequency clocks are needed in a single system, such as:

• Digital video broadcast (DVB)
• Wireless backhaul links
• High speed serial data links
• Cellular, 3G and 4G base stations
• Networking equipment
• Servers and storage devices

The 2308B-1DCGI8 is ideal for applications that require a high level of integration and flexibility, including:

• Data sheet measurement and test systems
• Embedded systems that require multiple frequencies
• Broadband communications
• High speed wireless communication networks
• Multi-standard RF systems
• High frequency clock sources

Working Principle

The 2308B-1DCGI8 can be used to generate multiple microprocessor, audio, or media clocks simultaneously, allowing multiple signal and frequency transitions within a single system. The device can generate up to 8 differential or 16 single-ended clock outputs over a wide range of frequencies, from a few KHz to 600MHz.

The 2308B-1DCGI8 consists of two main components: a voltage-controlled crystal oscillator (VCXO) and a programmable synthesizer. The VCXO provides the device with stable and accurate reference frequencies, while the synthesizer controls the output frequencies and provides clock and data multiplexing capability. The output frequencies are programmable using a 3-wire serial interface, allowing for easy customization.

The device also features an integrated PLL, which allows for the mixing of frequencies from different sources to generate a variety of output clocks. This allows for flexible frequency generation, including the ability to mix and match different PLL reference frequencies, as well as to generate a wide range of mixed and fractional frequencies. The PLL can also be used to generate jitter-free clocks with low noise, as well as to synchronize multiple clock sources.

Conclusion

The 2308B-1DCGI8 is a high performance Clock Generator, Frequency Synthesizer, and PLL choice for applications that require a wide range of frequencies and scalability. It provides the user with stable and accurate reference frequencies, as well as the flexibility to generate multiple clock outputs and a wide range of frequencies. With its integrated PLL and serial interface, the 2308B-1DCGI8 offers an easy-to-use and flexible clock generation solution.
