Functional Description

The CY22393, CY22394, and CY22395 are a family of parts designed as upgrades to the existing CY22392 device. These parts have similar performance to the CY22392, but provide advanced features to meet the needs of more demanding applications.

The clock family has three PLLs which, when combined with the reference, allow up to four independent frequencies to be output on up to six pins. These three PLLs are completely programmable.

The CY223931 is the CY22393 with NiPdAu lead finish.

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.
