CY2308SC-2

Product Overview

The Cypress Semiconductor Corp CY2308SC-2 is a surface-mount integrated circuit intended for clock distribution and zero-delay buffering in 3 V to 3.6 V digital systems. It accepts LVCMOS or LVTTL input signals and provides LVCMOS outputs with a 1:8 input-to-output ratio, supporting frequencies up to 133.3 MHz. The device includes PLL functionality and divider/multiplier capability, and is packaged in a 16-SOIC package with a 3.90 mm body width for surface-mount assembly.

Key Features

• The device is a fanout buffer and zero-delay buffer.
• Input logic levels are LVCMOS and LVTTL; output logic levels are LVCMOS.
• The input-to-output ratio is 1:8, with one circuit and non-differential input/output.
• Maximum operating frequency is 133.3 MHz.
• PLL and divider/multiplier functions are included.
• Supply voltage range is 3 V to 3.6 V, and operating temperature range is 0°C to 70°C.
• Surface-mount 16-SOIC package, 3.90 mm width.

Applications

• Clock distribution in digital logic boards where a single reference clock must be replicated to multiple LVCMOS loads.
• Timing fanout for 3 V to 3.6 V logic subsystems operating up to 133.3 MHz.
• Zero-delay buffering of a common system clock in board-level timing paths that require a single input and eight outputs.

Design & Procurement Notes

Designers should verify that the system clock does not exceed 133.3 MHz and that the board supply remains within 3 V to 3.6 V. The LVCMOS/LVTTL input and LVCMOS output levels should match the connected logic, while the non-differential 1:8 buffering arrangement requires attention to trace loading and output fanout. The 0°C to 70°C operating range and 16-SOIC surface-mount package should be considered for assembly and thermal layout.
