CY2304SXC-1

Product Overview

The Infineon Technologies CY2304SXC-1 is a surface-mount clock fanout buffer for distribution of a single-ended clock signal. It provides a 1:4 input-to-output ratio, zero-delay buffer functionality, and a PLL, while operating from a 3.0 V to 3.6 V supply. The device is rated for a maximum frequency of 133.3 MHz and an operating temperature range of 0°C to 70°C. It is housed in an 8-SOIC package with a 0.154" (3.90 mm) width.

Key Features

• Fanout buffer and zero-delay buffer for clock distribution
• PLL included for clock timing
• 1:4 input-to-output ratio with a single circuit
• Single-ended clock input and single-ended clock output
• Maximum frequency of 133.3 MHz
• 3.0 V to 3.6 V supply voltage range
• 0°C to 70°C operating temperature range
• Surface-mount 8-SOIC package with 3.90 mm width

Applications

• Clock distribution in embedded controller boards
• Reference clock replication for peripherals in single-board systems
• Fanout of a system clock to logic modules in data-acquisition hardware
• Clock synchronization paths in test and measurement instruments

Design & Procurement Notes

When using the CY2304SXC-1, confirm that the clock source is a single-ended signal and that the operating frequency does not exceed 133.3 MHz. The 1:4 input-to-output ratio provides a one-to-four fanout relationship, while the no divider and no multiplier configuration means the device does not provide frequency division or multiplication. The 3.0 V to 3.6 V supply range and 0°C to 70°C operating temperature range should be checked against the board power and ambient environment. The surface-mount 8-SOIC package and 3.90 mm width affect placement, and the PLL and zero-delay buffer characteristics should be considered during timing analysis.
