DS1091LUB-019/V+ is a Clock Generator which belongs to the Clock/Timing category and offers a wide range of clock generation and frequency synthesizing capabilities. It is a dual output, low jitter, programmable frequency synthesizer that supports both unbalanced and balanced clock synthesis. The DS1091LUB-019/V+ is used in applications where exact timing is critical such as digital audio, data communication, and computer systems.

Applications

The DS1091LUB-019/V+ is ideal for applications that require exact, reliable timing, such as computer systems, data communications, and digital audio equipment. It is also suitable for applications where precision and/or multiple clock frequencies are required, such as test and measurement instrumentation, data acquisition systems, broadcast equipment, and video production.

The clock generator is highly suitable for system designs requiring a wide variety of clock frequencies, either for clock buffering and system synchronization, or for interoperability with multiple processor types and architectures.

Working Principle

The DS1091LUB-019/V+ works by synthesizing a balanced output clock with very low jitter and minimal spurious signals. The programmable frequency synthesizing technology used in the clock generator allows the user to adjust the clock frequency to exactly match the required system clock.

The device provides selectable divide ratios and an integrated loop filter to ensure an optimized response time. This allows the user to adjust the frequency of the generated clock quickly and accurately without the need to reprogram the clock generator. Moreover, the device also includes a test output that can be used to verify system operation and a selectable duty cycle that enables characterization and testing of the generated clock.

The DS1091LUB-019/V+ is offered in a 16-pin TSSOP package and is designed for ease of use and low power consumption. It features integrated EMI filtering and a shutdown mode for further power savings.

Conclusion

The DS1091LUB-019/V+ is part of a family of Clock/Timing products from Maxim Integrated. It is a highly reliable, low power and low jitter clock generator/frequency synthesizer that is ideal for applications where exact timing is critical. It provides selectable divide ratios and integrated loop filters to guarantee optimized response time, as well as selectable duty cycle and EMI filtering to ensure optimal performance.
