CDCUN1208LPRHBT is a fully-integrated clock and timing device designed specifically as a feature-rich clock buffer, driver and multiplexer. It is designed to handle multiple inputs and outputs and provide low jitter and skew isolation, while eliminating the need for external components. This product is a superior solution for high speed digital design applications, such as Network-on-Chip (NoC) system interconnects, clock and timing synchronization, and other clock and timing operations.
Application Field
The CDCUN1208LPRHBT is suitable for applications where multiple clock inputs need to be isolated and buffered to ensure low-jitter, low-skew data synchronization. It is ideal for applications such as NoC systems, high definition video systems and data streaming over multiple interfaces. It is also suitable for applications ranging from clock synchronization and routing, clock splitting, and de-skewing between multiple clock networks. It is designed to support differential and single-ended signal inputs, and multiplexing between various clock networks.Working Principle
The CDCUN1208LPRHBT is designed to provide increased signal integrity and improved signal strength, while minimizing crosstalk and noise. The device has an integrated Clock Muting Controller and Programmable Symmetry Control which are used to provide various levels of switchover control. The device operates with input frequencies ranging from 8kHz to 1GHz. The CDCUN1208LPRHBT comprises 8 adjustable-depth registers and 3 data selectable input queues. The control registers are configured to provide adjustable phase offsets for each output buffer, thus providing low jitter and skew isolation when using multiple clock sources.
The device can be used to provide clock buffering and multiplexing capabilities, as well as clock synchronization when multiple sources are used. The clock muting controller allows for reduced power consumption and improved signal integrity when multiple sources are used. The programmable symmetry control is used to ensure that dynamic performance requirements are met for each clock output relative to its respective output buffer.
The CDCUN1208LPRHBT also features clock distribution, delay control, and clock multiplexing capabilities. The clock distribution capability allows the user to allocate clock inputs evenly among the outputs, while the delay control feature provides up to 7 ns of adjustable output delay. The clock multiplexing feature allows for multiple clock sources to be connected to the same outputs and allows for a redundant clock monitoring and failover control.
The CDCUN1208LPRHBT provides low-power operation and is optimized for high-speed digital designs, providing excellent signal integrity and minimal delay. The device is designed to help reduce overall system costs by eliminating the need for an expensive clock generator and buffers, while still providing excellent signal performance.
In summary, the CDCUN1208LPRHBT provides a feature-rich clock buffer, driver and multiplexer solution optimized for high-speed digital design applications. It offers increased signal integrity and improved signal strength, while providing low-power operation and minimal delay. The device is an excellent choice for applications where multiple clock inputs need to be buffered and synchronized, while eliminating the need for expensive clock generators and buffers.
