The DS1081LE+ is a programmable low-skew oscillator module with an integrated differential output buffer. It provides a flexible and adjustable clock solution, suited for applications such as telecom timing, high-speed interconnects, backplanes, broadcast or embedded applications. As a standard clock oscillator, the module can be set up to provide the optimized performance that a system requires.

Application Field

The DS1081LE+ is ideal for telecom timing applications. It can be used to provide up to 3.2GHz of low-skew clock distribution, with programmable precision frequencies up to 150MHz. Additionally, it can also be employed to generate high-rate phase-locked clocks for high-speed interconnects, such as gigabit Ethernet, SONET/SDH, and Fibre Channel standards.

The module is also suitable for broadcast and embedded clock applications. It can generate multiple frequency clocks and can precisely control the duty cycle and spread spectrum clock rates with high accuracy. This is especially useful when dealing with critical networks with heavy traffic, such as digital music and data broadcasting.

Working Principle

The DS1081LE+ is designed to provide a low-noise, low-skew, programmable oscillator clock. It uses an Integrated Voltage Controlled Crystal Oscillator (VCXO), allowing users to program the oscillating frequency, duty cycle and spread spectrum rate. The VCXO is also integrated with a differential output buffer, allowing it to be connected directly to the system for clock distribution. Additionally, the buffer\'s precision frequency allows it to achieve a wide frequency range with minimal noise and skew.

The module also features an integrated Temperature Compensated Crystal Oscillator (TCXO). This allows the module to operate over a wide temperature range, ensuring highly accurate timing over a wide range of environmental conditions. Additionally, the TCXO also helps to reduce timing jitter and allows the module to maintain its clock accuracy over long periods of time.

The DS1081LE+ also features a number of power management features. It includes built-in power-on reset and voltage monitoring, as well as an adjustable power-down option. Additionally, the module can be enabled and disabled via external control, allowing users to configure it to comply with their particular power requirement. These features enable the module to reduce its power consumption when not in use, allowing it to operate for longer periods of times without any loss in performance.

Conclusion

The DS1081LE+ is a highly versatile clock solution for applications such as telecom timing, high-speed interconnects, broadcast and embedded systems. Its integrated VCXO and TCXO allow it to generate low-skew, low-noise, programmable frequencies up to 150MHz, allowing users to easily configure the clock signal to fit their particular needs. Additionally, its integrated differential output buffer and power management features provide further flexibility, while its wide temperature range allows it to operate in a wide range of environments. The DS1081LE+ is therefore an ideal solution for a variety of clock and timing applications.
