Logic - Signal Switches, Multiplexers, Decoders

DS90CP02SP/NOPB can be classified under the above categories due to its ability to both switch and multiplex logic signals. The component has a total of 2 logic inputs, 2 logic outputs, and a differential clock. It is designed to be used in applications where logic level signals need to be transmitted through multiple stages while preserving their integrity. This device is a very high-speed differential switch which can handle very high frequency clock signals and distorted signals with low distortion.

Application Field

The DS90CP02SP/NOPB is often found providing a differential logic interface between typical logic components and higher speed data transmission systems. This component is highly versatile and can be used in a broad range of applications. Examples include PCI Express, Serial ATA, and Fibre Channel. The component is also well suited for less demanding and less complicated interface needs such as C bus and on-board clocking and synchronization circuitry.

Working Principle

The device uses a single 2-input to 2-output differential switch. The inputs are logic inputs that can be either active high or active low. The switch is controlled by a differential clock. The clock level is set using the clock select pins. The differential clock is used to create a non-overlapping, two-phase clock duty cycle. This two-phase clocking duty cycle is used to multiplex the logic level signals between the two outputs. The differential switch has two differential outputs, which are the final outputs. When a logic level signal is present on one of the inputs, the switch will open and allow the logic signals to travel through the switching transistor and output one of the differential signals. The opposite output will remain low during this time. With the clock switching to the opposite phase, the signals will be output to the other output. This process is ongoing, allowing both logic signals to be present at both outputs at any given time.

Conclusion

DS90CP02SP/NOPB is a very reliable and advanced component which can be used for different applications when performing logic level signal transmission using a differential switch and clock. This component offers excellent performance for data clocking, C bus and other digital interface needs. It also provides good signal integrity, allowing for high speed switching and distortion reduction. Its versatility makes it a great component for different applications.
