CY2304SXI-1T

Product Overview

The CY2304SXI-1T from Infineon Technologies is an 8-SOIC clock fanout buffer and zero delay buffer intended for distributing a single clock signal to multiple downstream timing loads. It uses a clock input and provides clock outputs with a 1:4 input-to-output ratio, supporting frequencies up to 133.3 MHz. The device operates from a 3 V to 3.6 V supply and is specified for an ambient temperature range of -40°C to 85°C.

Key Features

• Fanout buffer and zero delay buffer function
• Clock input to clock output with 1:4 ratio
• Maximum supported frequency of 133.3 MHz
• Single circuit with non-differential input and output
• Integrated PLL
• 3 V to 3.6 V supply range
• -40°C to 85°C operating temperature range
• 8-SOIC surface-mount package

Applications

• Clock distribution networks in digital boards that share one input clock with multiple synchronous logic devices.
• Fanout of a system clock to four downstream loads in embedded hardware using the 1:4 input-to-output ratio.
• Non-differential clock buffering in 3 V to 3.6 V surface-mount designs where a single circuit handles the timing path.

Design & Procurement Notes

Design considerations should focus on matching the 3 V to 3.6 V supply, verifying that the incoming clock frequency does not exceed 133.3 MHz, and allocating board space for the 8-SOIC footprint. Because the input and output are non-differential, the layout should preserve clock integrity with short trace lengths and careful return paths. The 1:4 output ratio supports one-to-four fanout, while the zero delay buffer and PLL functions address clock distribution rather than frequency division or multiplication.
