CY2304SC-1

Product Overview

The CY2304SC-1 from Cypress Semiconductor Corp is a surface-mount clock buffer classified as a fanout buffer and zero-delay buffer. It accepts a single clock input and provides a 1:4 input-to-output ratio in a non-differential configuration. The device is specified for a maximum clock frequency of 133.3 MHz and operates from a 3 V to 3.6 V supply. It is housed in an 8-SOIC package with a 3.90 mm body width and is rated for an operating temperature range of 0°C to 70°C.

Key Features

• Fanout buffer and zero-delay buffer type for clock distribution
• Single circuit with a 1:4 input-to-output ratio
• Clock input and clock output interfaces
• Non-differential input and output configuration
• Maximum operating frequency of 133.3 MHz
• Supply voltage range of 3 V to 3.6 V
• Operating temperature range of 0°C to 70°C
• Surface-mount 8-SOIC package, 0.154 in, 3.90 mm width
• PLL function is included

Applications

• Distributing one clock signal to multiple logic devices on a board
• Replicating clock signals at or below 133.3 MHz in 3 V to 3.6 V digital subsystems
• Providing single-ended clock fanout where differential clock inputs are not required

Design & Procurement Notes

When selecting this device, confirm that the clock signal does not exceed 133.3 MHz and that the supply remains within 3 V to 3.6 V. The 1:4 ratio and non-differential clock interfaces mean the part is suited to single-ended clock fanout rather than differential clocking or division or multiplication. The 8-SOIC surface-mount package and 3.90 mm body width should be checked against available board area, land pattern, and reflow process. The 0°C to 70°C operating range should be compared with expected ambient conditions. The PLL function should also be considered during clock path planning.
