CY2305CSXA-1

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2305CSXA-1 is a low-cost 3.3V zero delay buffer manufactured by Infineon Technologies, originally designed by Cypress Semiconductor. It accepts one reference input and drives five low-skew buffered clock outputs using an internal phase-locked loop (PLL). The device operates within a frequency range of 10 MHz to 133 MHz and supports LVCMOS/LVTTL input signals with LVCMOS output levels. It is housed in an 8-pin SOIC package and functions as a fanout buffer for distributing high-speed clocks.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Zero input-output propagation delay achieved through on-chip PLL feedback
• Multiple low-skew outputs driven by a single reference input
• Compatible with Pentium-based systems and standard bus frequencies

Clock Generators, PLLs, Frequency Synthesizers Applications

• Distribution of high-speed clocks in CPU and PCI bus architectures
• Buffering reference clocks for multiple synchronous components
• System testing via test mode bypass capabilities

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'A' against official ordering tables, as it may denote tape-and-reel packaging or lead-free status. Confirm that the component meets current design requirements, noting that this family is generally not recommended for new designs. Ensure compatibility with existing PCB footprints and power supply specifications before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single reference clock must drive five outputs with minimal skew and zero input-to-output delay. Verify that the required operating frequency falls between 10 MHz and 133 MHz. Consider the -1H variant if faster rise and fall times are necessary for higher frequency stability.
