The CY2308SXI-3T is a high performance, low power single source low jitter clock generator, specially designed for usage in critical timing applications. It utilizes a PLL-based frequency synthesizer that is designed to generate multiple frequencies from a single clock input. Offering excellent phase balance and frequency accuracy, the CY2308SXI-3T is a particularly suitable choice for meeting stringent application requirements of Switching Fast Ethernet, 100Base-T, WAN and other similar applications.

The CY2308SXI-3T is powered by a low-noise analog PLL circuit, in which the main clock input is first amplified, filtered and divided before entering a phase detector. The frequency of the output clock is then adjusted by the analogue loop filter depending on the information provided by the phase detector, resulting in excellent frequency accuracy and jitter performance. In order to provide optimal jitter performance for critical timing applications, the device features integrated peak detect and video synchronizer blocks which clean up any remaining jitter on the chip\'s output. In addition, the device is protected from excessive power consumption, enabling it to meet the most demanding application requirements.

The CY2308SXI-3T provides programmable I2C register interface and SPI port for user configuration. It supports 5 output clocks including a variety of standard frequencies and output signal types, such as LVPECL, LVDS, and HCSL. The integrated 0-24VDC Supply Control Interface allows regulation of the voltage supplied to the output buffer, enabling improved flexibility in configuring the device in a wide range of applications.

The CY2308SXI-3T offers excellent noise immunity and cross-talk protection, making it an ideal choice for use in high-speed and densely populated applications. Setup and configuration of the device can be done via a readily available software utility, reducing the learning curve associated with its usage. With its high-reliability features, this low power clock generator is a reliable source of reference clocks for modern clocks and data communications applications.
