CDCU877AGQLT belongs to a series of field-programmable application-specific integrated circuits (FPASIC ™) designed by Microchip. It is an advanced network-wide synchronous clocking solution that integrates all the traditional components of a frequency synthesizer, clock distribution device, programmable clock buffer and delay line, into a single device. The integrated device supports the Synchronous Ethernet (IEEE 1588v2) as well as other low-cost network-wide clocking protocols, providing a highly reliable, low-power and cost-effective solution.

The CDCU877AGQLT can be used in a variety of digital system applications that require a consistent, highly accurate clock. It provides a cost-effective solution for the challenging low-power, short-delay, wide-range clocking requirements in high-speed serial and parallel data buses. It is also often used for synchronization in Wi-Fi, Ethernet and other communication systems. Its application range includes embedded network switches and routers, high-speed networking ASICs, industrial automation and video and audio processing.

The CDCU877AGQLT consists of 8 low-skew, single-ended clock buffers, each of which can be individually assigned to one of the 8 input clock sources. The chip also integrates a frequency synthesizer, digital dividers, adjustable clock-skew buffers and other components. It offers a wide range of output frequencies and clocking options, and supports user-defined clock outputs and independent programming of the delay line.

To provide clock synchronization across the network, the CDCU877AGQLT supports a variety of clocking protocols, including Synchronous Ethernet (IEEE 1588v2) and other low-cost clock synchronization solutions. It provides an optimized frequency synthesis algorithm and provides better frequency accuracy compared to traditional methods. It also offers advanced frequency division algorithms to minimize the number of required clock outputs.

In addition, the CDCU877AGQLT features a wide adjustable output delay range, allowing for better skew compensation within the system. It offers fine-tunable delay control andprogrammable clock outputs, allowing for direct synchronization with both local and remote clocks.

The CDCU877AGQLT is ideal for applications requiring high frequency accuracy, low power consumption and cost-effective solutions. Its integrated design simplifies the design and reduces system component cost. It also provides flexibility for designers to integrate different features with ease.
