CY2308SC-1

Product Overview

The Cypress Semiconductor Corp CY2308SC-1 is a surface-mount clock fanout buffer for single-ended timing distribution in digital systems. It supports a maximum frequency of 133.3 MHz and a 1:8 input-to-output ratio, using LVCMOS or LVTTL inputs and LVCMOS outputs. The device includes a PLL with bypass and operates from a 3 V to 3.6 V supply. It is packaged in a 16-SOIC package with a 3.90 mm body width for an operating temperature range of 0°C to 70°C.

Key Features

• Fanout buffer and zero delay buffer type for clock distribution.
• 1:8 input-to-output ratio for distributing a single clock signal.
• LVCMOS or LVTTL input logic with LVCMOS output logic.
• Maximum frequency rating of 133.3 MHz.
• PLL with bypass option.
• Single-ended design with no differential input or output.
• 3 V to 3.6 V supply voltage range.
• Surface-mount 16-SOIC package, 3.90 mm width.
• Operating temperature range of 0°C to 70°C.

Applications

• Distribution of a common clock to multiple digital logic devices in a board-level timing tree.
• Fanout buffering for single-ended LVCMOS or LVTTL clock signals.
• Clock signal distribution in systems operating up to 133.3 MHz.
• Timing buffering in designs using a 3 V to 3.6 V supply and a PLL bypass option.

Design & Procurement Notes

Design use should confirm that the incoming clock logic is LVCMOS or LVTTL and that the driven loads are compatible with LVCMOS outputs. The 3 V to 3.6 V supply range and 0°C to 70°C operating temperature range need to match the board power and thermal environment. For layout, verify the 16-SOIC surface-mount footprint and keep clock fanout paths controlled to support the 133.3 MHz maximum frequency. The PLL bypass option provides a configuration consideration when PLL bypass is required.
