The CDCLVC1108PWR is a high-performance dual-output low skew 1:8 differential clock buffer. It is designed with advanced capabilities to effectively buffer high-speed clock signals and provides high flexibility of input/output configurations. The CDCLVC1108PWR is an ideal device for applications that require a low-cost solution for driving multiple clock signals, such as telecom equipment, test and measurement equipment, and embedded designs.

The CDCLVC1108PWR is a dual-output low-skew 1:8 differential clock buffer. It features a wide operating temperature range from -40℃ to 125℃ and provides a 3.3V/2.5V logic-level compatible I/O interface. It has a low output-to-output skew of less than 100ps, allowing for signals to reach multiple devices with accurate timing and synchronization. The device has an adjustable output slew rate that can be programmed externally to reduce the switching noise created by the clock, while still providing a clean signal. It also features an internal power-on reset circuit, which ensures all device outputs remain in a known state during power-on.

The CDCLVC1108PWR’s differential inputs can accommodate signal levels as low as 220mV. This allows the device to accept inputs from various sources, including clock generators with varying output voltage levels and signal sources with different signal integrity levels. The device also has separate power and ground pins on each output bank, allowing for the outputs to be driven at different voltages.

The CDCLVC1108PWR’s main application field is in clock buffering and signal distribution. It can be used to buffer and distribute any clock signal, such as the master reference clock, the SYNCIN input, or another clock source. This can be done either by daisy-chaining devices or by cascading devices together, depending on the number of devices that need to be driven. This allows for multiple devices to be driven simultaneously with a low skew and with a common clock signal. Additionally, the output slew rate can be adjusted to reduce the switching noise caused by the clock.

The working principle of the CDCLVC1108PWR is to buffer and amplify the input clock signal, providing a low-skew, clean output clock signal. The device accomplishes this by using a differential input pair to accept the clock signal from the source, and then a series of PLL, voltage-level translators and buffers to further amplify, filter and shape the buffer output. This provides an amplitude-stable output clock signal that can be used to drive multiple devices with a low output-to-output skew. In addition, the device can also be programmed to reduce the output slew rate and switching noise created by the clock.

In summary, the CDCLVC1108PWR is a high-performance dual-output low-skew 1:8 differential clock buffer designed for applications that require a cost-effective solution for driving multiple clock signals. It has a wide operating temperature range and provides a 3.3V/2.5V logic-level compatible I/O interface. Its differential inputs can accept signals as low as 220mV and its adjustable output slew rate allows for the reduction of clock switching noise. It can be used in applications involving clock buffering and signal distribution, allowing for multiple devices to be driven with a low output-to-output skew.
