CY2308SXI-3

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2308SXI-3 is a 3.3V Zero Delay Buffer manufactured by Infineon Technologies, housed in a 16-pin SOIC package. It operates within an input frequency range of 10 MHz to 133 MHz and supports industrial temperatures from -40°C to +85°C. The device features two banks of four outputs each, controlled by select inputs S1 and S2. In the –3 configuration, connecting Bank A to the feedback pin yields 2X reference frequencies on Bank A and Reference frequencies on Bank B; connecting Bank B provides 4X reference on Bank B and 2X reference on Bank A. Electrical characteristics include a typical cycle-to-cycle jitter of 400 ps at 66.67 MHz with a 15 pF load.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Configurable frequency multiplication providing 2X or 4X output clocks relative to the reference input
• Two independent three-stateable output banks for flexible clock distribution
• Adjustable zero input-output propagation delay via capacitive loading on the feedback pin

Clock Generators, PLLs, Frequency Synthesizers Applications

• PC and workstation clock distribution systems
• Datacom and telecom high-performance applications
• System testing requiring direct reference clock bypass

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm that the specific ordering suffix matches the required industrial temperature grade and package variant. Review the datasheet revision history for any updates to electrical parameters or packaging specifications prior to finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when 2X or 4X clock multiplication is required alongside low skew distribution. Ensure the application load capacitance aligns with the specified 15 pF or 30 pF limits for the target operating frequency. Verify that the power supply voltage remains strictly between 3.0 V and 3.6 V to maintain timing accuracy and prevent damage.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the CY2308 family of 3.3V Zero Delay Buffers originally developed by Cypress Semiconductor Corporation. The series includes variants offering reference, 2X, and 4X frequency multiplication capabilities. The –3 variant specifically enables dual-bank frequency scaling, making it distinct from single-ratio buffers like the –1 or –4 models.
