CY23S08SI-1H

Clock Buffers, Drivers Overview

The CY23S08SI-1H is a PLL-based zero delay clock buffer manufactured by Cypress Semiconductor Corp. It accepts an LVCMOS or LVTTL input and provides eight true LVCMOS outputs in a 16-SOIC package. The device operates on a single 3V to 3.6V supply voltage and supports an operating temperature range of -40°C to 85°C. Designed for low-skew clock distribution, it features adjustable propagation delay via the feedback capacitor and includes three-stateable output banks controlled by select inputs.

Clock Buffers, Drivers Feature Summary

• Zero input-output propagation delay adjustable by capacitive load on FBK input
• Eight LVCMOS outputs with two three-stateable banks of four outputs each
• Operates within 3V to 3.6V supply voltage range
• Industrial temperature rating from -40°C to 85°C

Clock Buffers, Drivers Applications

• High-speed digital systems requiring precise clock synchronization
• Embedded processors and controllers needing low-jitter clock distribution
• Communication equipment utilizing LVCMOS/LVTTL interfaces

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'SI' against official Cypress documentation to confirm industrial temperature grade and lead-free status. Ensure the 16-SOIC package width matches the 0.154-inch specification required for the PCB footprint. Confirm RoHS compliance through the manufacturer's current datasheet rather than relying solely on distributor descriptions.

Clock Buffers, Drivers Selection Notes

Select this component when a single reference clock must be distributed to eight loads with minimal skew. The CY23S08SI-1H is suitable for designs requiring three-state control over output groups. Verify that the system input signal meets LVCMOS or LVTTL voltage levels and that the operating environment falls within the specified -40°C to 85°C range.

Clock Buffers, Drivers Part Context

This part belongs to the 23S series of zero delay buffers from Cypress Semiconductor. It shares architectural similarities with the CY2308 and CY23S08 families but is distinguished by its specific suffix indicating industrial temperature capability and packaging variant. It serves as a direct replacement for legacy clock drivers requiring eight buffered outputs with programmable drive strength.

Clock Buffers, Drivers Replacement Considerations

The ASM5I23S08A-1H-16-ST from Alliance Semiconductor offers similar functionality with an SOIC-16 package. Verify pin compatibility and electrical parameters before substitution. Other Cypress parts like the CY23S08SXC-2H provide comparable performance but may differ in temperature range or package type.
