Functional Description

The CY23S09 is a low cost 3.3 V zero delay buffer designed to distribute high speed clocks and is available in a 16-pin SOIC package. The CY23S05 is an 8-pin version of the CY23S09. It accepts one reference input, and drives out five low skew clocks. The -1H versions of each device operate at up to 100 and 133 MHz frequencies and have higher drive than the -1 devices.

Dear valued customer,

Thank you for choosing our products. They come with all the know-how and passion that our engineers have put into it. As you probably already know, Cypress is now Infineon. This is a major step for our company, but also for the good of you. 

Reliability and business continuity are of utmost importance for us. Hence, we remain fully committed to honoring existing customer and distributor relationships. This includes offering the legacy Cypress product portfolio. We thank you very much for your trusting support.
