CY2308SI-3

Product Overview

The CY2308SI-3 from Cypress Semiconductor Corp is a surface-mount integrated circuit specified as a fanout buffer and zero-delay buffer. It provides a single circuit with a 1:8 input-to-output ratio, accepts LVCMOS or LVTTL input signals, and delivers LVCMOS outputs. The device includes a PLL and is rated for a maximum frequency of 133.3 MHz. It operates from a 3 V to 3.6 V supply and is specified for -40°C to 85°C. The package is 16-SOIC with a 0.154 inch, 3.90 mm width, and the mounting type is surface mount.

Applications

• Distributing one non-differential reference clock to eight LVCMOS loads on a printed circuit board
• Buffering and replicating a system clock in LVCMOS digital logic subsystems

Design & Procurement Notes

When selecting the CY2308SI-3, verify that the upstream clock source is LVCMOS or LVTTL and that the downstream loads are compatible with LVCMOS outputs. The 1:8 ratio means the device is intended for one input clock fanned out to eight outputs rather than multiple independent circuits. Designers should also confirm that the required clock frequency does not exceed 133.3 MHz and that the board supply remains within 3 V to 3.6 V. Because the inputs and outputs are specified as non-differential, layout should preserve clock signal quality. The 16-SOIC surface-mount footprint and -40°C to 85°C operating range should be considered during PCB placement and thermal review. Use the exact manufacturer part number and package when documenting the board assembly and bill of materials.
