CYW256OXCT is a low-skew, low-jitter clock buffer with integrated voltage-controlled burn-in oscillator. The device is ideal for applications that require low jitter and tight phase matching between outputs. This product is available in 256-pin ebwg (Enhanced B/W Graphics) package and supports multiple reference clock sources across a wide voltage range.

The CYW256OXCT features two separately programmable output clock outputs for applications that need separate clocks. The device also features an adjustable phase shift (in 5-degree increments) and adjustable output slew rate selection. The output options are flexible and the onboard configuration can be changed quickly to suit the clock requirements of the application.

The CYW256OXCT has very low jitter and is ideal for applications where there is minimal phase noise or wideband frequency shifts. The device is designed to achieve very high-frequency output stability (across all parts of the frequency band) and wideband edge rate stability. The output frequency range is also very wide, enabling applications with spectral components over a wide range of frequencies.

The principle of operation and application field of CYW256OXCT is clock buffering. It is typically used in applications where the accuracy of a clock signal is critical. CYW256OXCT can be used for multiple reference clock sources in systems where synchronization and accuracy are paramount. It is often employed in SerDes (serializer/deserializer) and high-performance memory applications. Its wide frequency range combined with low jitter and fast edge rates make it an ideal choice for high-performance Ethernet and Fibre Channel applications.

To ensure accurate synchronization, the clock outputs of the CYW256OXCT can be programmed to operate in both the synchronous and asynchronous modes. In synchronous mode, multiple clocks are propagated in single-master mode. In asynchronous mode, a single clock source is divided into multiple frequency outputs, allowing each output to operate independently. If needed, the oscillator can also be programmed to restrike at a pre-determined rate.

The CYW256OXCT also features on-chip thermal and electrical protection, providing robust system protection from overvoltage and over-temperature conditions. It includes an on-board voltage monitoring feature that allows continuous monitoring of the supply voltage, reducing system cost and power consumption. Moreover, the device is RoHS compliant, allowing system designers to integrate the device into their project with minimal environmental concerns.

In conclusion, CYW256OXCT is a low-skew, low-jitter clock buffer with integrated voltage-controlled burn-in oscillator. It is designed for use in applications where accuracy and synchronization are key. The device offers wide frequency range, low jitter, fast edge rates, and robust protection, making it an ideal choice for high-performance Ethernet and Fibre Channel applications.
