The DS1087LU-40K+T Chip is a versatile, multi-output, phase-locked loop clock generator with an integrated phase-aligner. It is used in applications such as communications, multimedia, embedded computing, and servers. The DS1087LU-40K+T combines a robust and versatile phase-locked loop circuit with an advanced, low-power analog phase-aligner to provide accurate, low skew, integral clocking for multi-output applications

The DS1087LU-40K+T Chip enables the design of highly integrated systems with low-skew, multiple clock outputs for a wide range of clock rates. The chip offers programmable , reliable, and accurate output clocks using a variety of reference frequencies and available input triggers. The chip also supports several output formats and multiple frequencies from a single device to meet the needs of most applications. Additionally, the chip features several input and output functions to facilitate simple and reliable operation and integration into existing systems.

The DS1087LU-40K+T features two oscillator clocks - a reference clock and an input clock - and a phase detector. The reference oscillator clock is a low-jitter, 180° phase-skew clock with a typical 24 Hz to 48 MHz frequency range. The input clock is used to phase-lock the reference oscillator by providing a phase-lock signal to the phase detector. The phase detector then compares the phase of the reference oscillator with the phase of the input clock and adjusts the phase of the reference oscillator accordingly until the phases are aligned, resulting in a phase-locked loop.

The phase-lock signal generated by the phase detector is then fed to the integrated phase-aligner. The phase-aligner is a sophisticated analog circuit that adjusts the phase of the reference oscillator clock by providing precise, low-skew outputs. It does this by comparing the phase of each output clock to the phase of the reference oscillator and adjusting it to the desired phase. This ensures that all the output clocks are in precise phase alignment. The phase-aligner also allows precise frequency synthesis and can be used to generate multiple clock frequencies from a single reference oscillator.

The DS1087LU-40K+T can be used in a wide range of applications, including communications, multimedia, embedded computing, and servers. The chip is well-suited for applications that require multiple clocks with precise and low skew. The integrated phase-aligner ensures accurate and reliable operation, while the low power consumption makes it ideal for battery-powered designs. The wide range of compatible frequencies, multiple output formats, and easy integration into existing systems makes the DS1087LU-40K+T a popular choice for many projects.
