CY2305CSXC-1

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2305CSXC-1 is a commercial-grade, 3.3 V zero delay clock buffer manufactured by Infineon Technologies (formerly Cypress). It operates within an ambient temperature range of 0 °C to 70 °C and accepts a single reference input to drive five low-skew outputs. The device supports operating frequencies from 10 MHz up to 100 MHz with a 30 pF load, or up to 133.33 MHz with a 10 pF load. Electrical characteristics include a typical cycle-to-cycle jitter of 50 ps at 66.67 MHz, a maximum output-to-output skew of 200 ps, and a supply current of 32 mA when unloaded at 66.67 MHz. It utilizes an on-chip phase-locked loop for clock distribution.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Provides zero input and output propagation delay through internal PLL feedback
• Features multiple low-skew buffered clock outputs driven by a single reference input
• Includes power-down mode that reduces supply current when no rising edges are detected on the reference pin

Clock Generators, PLLs, Frequency Synthesizers Applications

• Distribution of high-speed clocks in digital systems
• Die replacement for legacy CY2305 devices
• Systems requiring low-skew clock synchronization

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type, temperature grade, and drive strength. Ensure the component meets the required RoHS compliance standards for the target application environment. Cross-reference the datasheet revision to validate electrical parameters before finalizing procurement specifications.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component for applications requiring a 3.3 V zero delay buffer with five outputs in an 8-pin SOIC package. Confirm that the system load capacitance aligns with the specified frequency limits, as higher loads restrict the maximum operating frequency to 100 MHz. Verify that the commercial temperature range of 0 °C to 70 °C satisfies the operational environmental requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the CY2305C family, which serves as a die replacement for the original CY2305 series. It is designed specifically for distributing high-speed clocks with minimal skew. The CY2305C variant provides five outputs, whereas the related CY2309C offers nine outputs in a larger package. Both share similar functional architectures and voltage specifications.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The CY2305CSXC-1 functions as a direct die replacement for the standard CY2305. When substituting, ensure the load capacitance matches the original design to maintain zero delay performance. Note that the -1H variants offer faster rise and fall times compared to the standard -1 drive strength.
