CY28331OXC is a low-skew, high-performance clock and timing device designed to provide versatile and flexible solutions for a wide range of clocking needs. The device combines multiple, independent clock output signals with various features such as phase alignment, phase noise, and frequency switching. CY28331OXC is highly integrated clocking solution that reduces design complexity while providing flexibility and high performance.

The CY28331OXC family of timing devices are designed to provide a reliable distribution of high-quality, low-skew clock signals to multiple system components. This device incorporates an internal reference clock oscillator, an advanced digital PLL and an output driver for generating multiple independently programmable clock output signals. This device consists of three parts: the Clock Generator, Phase-Locked Loop (PLL) and Output Driver.

The Clock Generator is the heart of the CY28331OXC. It’s a precise low-jitter, high frequency frequency synthesizer which is used to generate the precise frequency for the required clock outputs. The PLL is then used to multiply the reference frequency to the required output frequencies. The Output Driver is used to condition and drive the clock output signals. It contains multiple voltage control oscillators and divider circuits to generate multiple independently programmed output frequencies. It also provides an adjustable slew rate and drive level range for each output.

The CY28331OXC device provides an easy and quick way to generate multiple high frequency clock signals with precise timing within a single package. Typical applications where the CY28331OXC device can be used include Network Synchronization, Synchronous Ethernet, SONET/SDH, Broadband Routers, Video processing, and Clock Recovery. The device features fine tuning capabilities to provide adjustment of frequency and phase of the output signals, allowing for precise system tuning to meet design specifications.

This device can be used to divide the reference clock into multiple clocks, each with its own frequency, with precise phase alignment and programmable frequency variation. The on-chip PLL and Output Driver combine to provide flexibility in the control of output clocks. The Clock Generator allows the user to select the reference frequency to be used, the required number of clock outputs, the output frequencies, and to modify the output signal waveforms. All of this is done using an external pin interface or a serial port.

The CY28331OXC offers a wide range of features and benefits for its usage in clocking applications. It can reduce cost, system complexity, board area and power consumption when compared to discrete solutions. The device is easy to use and provides fast, accurate and repeatable performance with no additional system components. The CY28331OXC is the perfect device for designers looking for low-skew, high-performance clock and timing device with reliable signal distribution.
