CY2305CSXA-1T

Product Overview

The CY2305CSXA-1T from Cypress Semiconductor Corp is a surface-mount zero delay buffer and fanout device intended for clock distribution tasks in digital boards. It accepts LVCMOS or LVTTL input signals and provides LVCMOS outputs, supporting frequencies up to 133 MHz while operating from a 3 V to 3.6 V supply. The part is housed in an 8-SOIC package with a 0.154 inch, 3.90 mm body width, which supports compact placement on surface-mount assemblies and simplifies routing near clock sources.

Key Features

• Zero delay buffer and fanout device for distributing clock signals to multiple downstream loads.
• Maximum frequency of 133 MHz for clock distribution paths.
• LVCMOS or LVTTL input compatibility with LVCMOS output signaling.
• Supply voltage range of 3 V to 3.6 V.
• Surface-mount 8-SOIC package with 0.154 inch, 3.90 mm width.

Applications

• Board-level clock fanout where a buffered clock is distributed to multiple LVCMOS loads.
• Timing signal buffering in digital subsystems using LVCMOS or LVTTL clock inputs.
• Clock distribution between logic blocks operating from 3 V to 3.6 V supplies.
• Compact surface-mount clock distribution circuitry requiring an 8-SOIC footprint.
• Clock buffering in systems constrained by a maximum frequency of 133 MHz.

Design & Procurement Notes

When selecting the CY2305CSXA-1T, verify that the incoming clock source presents LVCMOS or LVTTL levels and that downstream devices accept LVCMOS outputs. Keep the operating frequency at or below 133 MHz and provide a stable supply within 3 V to 3.6 V. The 8-SOIC surface-mount package requires standard SOIC footprint and assembly handling, so confirm board spacing and land pattern compatibility before layout. These checks help ensure the buffer is used within its stated electrical and mechanical conditions.
