CY2308SXI-5HT

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2308SXI-5HT is a 3.3V Zero Delay Buffer designed for high-speed clock distribution in PC, workstation, and datacom applications. It features an on-chip PLL that locks to a reference clock input (REF) and provides eight LVCMOS outputs divided into two banks of four. The device operates within a frequency range of 10 MHz to 133 MHz with a supply voltage of 3.0 V to 3.6 V. It supports industrial temperature operation from -40 °C to 85 °C. Outputs are three-stateable via select inputs, allowing the REF signal to be passed directly for testing. The part is housed in a 16-pin SOIC package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Zero delay buffer architecture with adjustable input-output propagation delay via capacitive load on the feedback pin
• Two independent banks of four low-skew outputs controlled by external select inputs
• Integrated power-down mode that reduces current consumption when no rising edges are detected on the reference input

Clock Generators, PLLs, Frequency Synthesizers Applications

• PC and workstation clock distribution systems
• Datacom and telecom equipment requiring precise clock synchronization
• High-performance digital circuits needing multiple buffered clock signals
