The 853016AMLFT is a synchronous clock buffer IC designed for applications like clock distribution, clocking and fan-out. Synchronous buffers ensure that the transmitted data pattern is the same as the received data pattern, and are usually used for clock distribution. In this article we will discuss the application field of this type of IC, as well as its working principle.

Application Field

The 853016AMLFT is by definition a clock buffer IC, which means that it extends the output range of a clock. This IC can expand the range of one clock or of the system\'s multiple clock source synchronously. Furthermore, is can be used to reduce system noise and can improve the noise margin of the system. In this regard, it has been used in clocks and clock distribution applications, as well as various timing and system performance applications, like time base distribution and bus speeds.

This IC is especially useful in systems that require a single source of clock to drive multiple peripheral chips simultaneously. In such cases, this IC can be used to generate copies of the clock at different voltage stages and different frequencies in order to ensure that all devices are receiving the correct voltage and frequency necessary for optimal system performance. It is thus an integral part of Clock/Timing systems like Aerospace, Automotive, and Military applications.

Working Principle

The 853016AMLFT works on the principle of system synchronization, wherein it synchronizes the clocks in one system with the clocks in another system. The IC ensures that the transmitted clock is the same as the received one in order to ensure optimal performance. It works by receiving a clock signal from an oscillator, and then the IC distributes the signal to multiple outputs with the same frequency and phase. The IC contains an internal Schmitt trigger that assures that the output has a fast edge rate, thus eliminating the need for external circuitry.

The IC has two independent inputs that can be connected to a crystal oscillator to provide two clock sources. The two clocks are compared by the IC and a synchronous delay is generated correspondingly. The outputs are selectable between single-ended, dual-ended and differential outputs.

The IC is also capable of spreading the clock signal over the air, with very high accuracy and low intrinsic jitter, thus making it ideal for high-bandwidth applications. The IC has an adjustable output distribution chain with programmable de-skew and minimum required delays. Furthermore, the power saving modes help reduce power consumption of the IC, thus leading to improved system efficiency. The IC also makes use of a spread spectrum clock generator to reduce EMI.

Conclusion

The 853016AMLFT is a synchronous clock buffer IC designed for applications like clock distribution, clocking and fan-out. It is especially useful in systems that require a single source of clock to drive multiple peripheral chips simultaneously. It works on the principle of system synchronization and distributes the signal to multiple outputs with the same frequency and phase. Furthermore, it is capable of spreading the clock signal over the air, with very high accuracy and low intrinsic jitter, thus making it ideal for high-bandwidth applications.
