Clock/Timing - Clock Buffers, Drivers

The requirement to transfer clock signal across different printed circuit boards (PCBs) with high accuracy and minimal skew is a major concern in many high-speed digital systems. In order to fulfill this requirement, clock buffers and drivers were invented that help localized signal routing and also reduce the effects of noise on the clock signal. One such clock buffer used in many circuit boards is the CDCLVC1108PW.

The CDCLVC1108PW is a low-power, low-noise, low-skew, voltage-controlled crystal oscillator (VCXO) clock buffer integrated circuit from Texas Instruments. It was designed to help transfer clock signals with high accuracy and minimal skew across different PCBs. It is available in multiple configurations such as single (1:1), differential (1:2), and dual (2:2) output drive. Its low voltage operation allows it to be used in multiple applications such as SerDes, cables, trace routing, and PCBs.

The basic working principle of the CDCLVC1108PW is simple. It consists of an oscillator that produces a clock signal which is then buffered and transmitted out of the IC. It has multiple inputs that can be used to receive clock signals from external sources such as quartz crystal oscillators and voltage-controlled crystal oscillators (VCXOs). It has a differential output that can be used to transmit the clock signal to other devices on the same or different PCBs. The VCXO provides an adjustable frequency that can be used to fine-tune the output frequency of the clock signal. It also has an integrated phase-locked loop (PLL) that helps to reduce jitter and improve signal integrity.

The CDCLVC1108PW can be used in a variety of applications such as in audio, video, and high-speed digital systems. It is used to help transfer clock signals with minimal skew and high accuracy between different PCBs, thus reducing the effects of noise on the clock signal. It is also used to aid proper synchronization in multi-board systems. It is available in multiple configurations such as single (1:1), differential (1:2), and dual (2:2) output drive, making it ideal for most systems.

The CDCLVC1108PW clock buffer from Texas Instruments is an excellent choice for transferring clock signals between PCBs. It can be used to reduce the effects of noise on the clock signal and also to improve signal integrity. It is available in multiple configurations and can be used for a variety of applications. Its adjustable frequency and low voltage operation make it a great choice for many high-speed digital systems.
