Functional Description

The CY23EP05 is a 2.5 V or 3.3 V zero delay buffer designed to distribute low-jitter high-speed clocks and is available in a 8-pin SOIC package. It accepts one reference input, and drives out five low-skew clocks. The –1H version operates up to 220 (200) MHz frequencies at 3.3 V (2.5 V), and has a higher drive strength than the –1 devices. All parts have on-chip PLLs which lock to an input clock on the REF pin. The PLL feedback is on-chip and is obtained from the CLKOUT pad.

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.
