The CDC204DW is a buffer/driver for clock and high-speed data. It is an integrated combination of data and clock regeneration circuits, buffer amplifiers, and high and low speed output drivers. It has been specifically designed for applications where superior performance, low power and wide supply voltage ranges (2.5V to 5.5V) are required.

CDC204DW has a wide application field. It is ideal for connecting clock signals between high-speed interface sources, such as advanced interface controllers (AICs) and advanced serial port cards (ASPs), and other clock-dependent digital and analog ASICs or DSPs. It can be used to drive high-speed processor cores and for other high-performance digital signal processing (DSP) applications. CDC204DW can also be used for high-speed data synchronization, such as in multimedia applications.

CDC204DW buffers/drivers are known for their high signal integrity and low power. The device features an advanced circuit design to reduce switching noise and to minimize signal distortion so as to provide excellent jitter and signal integrity performance. The advanced signal regeneration technique can help reduce the effects of fan-in loading and signal distortion caused by long trace lengths. And the device supports edge-controlled output frequency selection, so you can determine the output frequency even if the clock signal edge rate is different. The adjustable driver skew further ensures high signal integrity between different output drivers in the device.

The working principle of the CDC204DW is based on the principle of clock and data regeneration. The device uses an advanced clock regeneration circuit to convert the incoming clock signal into an output clock signal of the desired frequency, phase, and duty cycle. The data regeneration circuit is designed to eliminate any observed phase jitter, by sampling the data multiple times and providing an error-free output.

The CDC204DW also features a low-power shutdown mode, allowing the device to be powered down when not in use. This is beneficial for systems that require low power or have limited energy resources. When in shutdown mode, the device consumes less than 0.2mW of power.

Overall, the CDC204DW is a highly versatile clock and high-speed data buffer/driver. With its advanced features and wide supply voltage range, it is an ideal solution for a variety of applications, from high-end processors to multimedia devices. Its low power consumption, excellent signal integrity, and adjustable output shift make it a great choice for systems experiencing high loading or long trace lengths.
