CY2304SXI-2

Product Overview

The Cypress Semiconductor Corp CY2304SXI-2 is a PLL-based clock driver for single-ended clock distribution tasks. It combines a fanout buffer and zero-delay buffer function in one circuit, accepting a clock input and producing four clock outputs in a 1:4 ratio. The device supports a maximum frequency of 133.3MHz, operates from a 3V to 3.6V supply, and is specified for temperatures from -40°C to 85°C. It uses an 8-SOIC surface-mount package with a 3.90mm package width for board layouts that require replicated clock signals without differential input or output conversion.

Key Features

• PLL-based clock driver with fanout buffer and zero-delay buffer functionality.
• Single clock circuit with a 1:4 input-to-output ratio, providing four clock outputs from one clock input.
• Supports a maximum frequency of 133.3MHz for timing distribution.
• Single-ended clock input and single-ended clock outputs; no differential input or differential output.
• Operates from a 3V to 3.6V supply and is specified for temperatures from -40°C to 85°C.
• Surface-mount 8-SOIC package with 3.90mm width, divider and multiplier capability.

Applications

• Clock distribution in single-ended digital assemblies that need one clock input replicated to four outputs.
• Board-level timing paths that use a zero-delay buffer function in a single-ended clock architecture.
• PLL-based clock subsystems that require divider or multiplier capability in a single circuit.

Design & Procurement Notes

Design considerations should begin with the 3V to 3.6V supply requirement and the 133.3MHz maximum frequency, then confirm that the application uses single-ended clock input and output rather than differential signaling. The 1:4 fanout ratio supports four loads from one circuit, but the 8-SOIC, 3.90mm surface-mount package must fit the board area and mounting constraints. The -40°C to 85°C temperature range should be checked against the expected operating environment. For procurement, specify the exact part number, package, supply voltage, frequency limit, and fanout requirement so the selected device matches the timing architecture without assumptions about differential capability or additional outputs.
