General Description

The CY22801 is a flash-programmable clock generator that supports various applications in consumer and communications markets. The device uses the Cypress-proprietary PLL along with Spread Spectrum and VCXO technology to make it one of the most versatile clock synthesizers in the market. The device uses a Cypress-proprietary PLL to drive up to three configurable outputs in an 8-pin SOIC.

The CY22801 is programmed with an easy-to-use programmer dongle, the CY36800, in conjunction with the CyClocksRT™ software. This enables fast sample generation of prototype builds for user-defined frequencies. Cypress’s value-added distribution partners and third-party programming systems from BP Microsystems, HiLo Systems, and others, can also be contacted for large production quantities. A JEDEC file needs to be configured to program CY22801, which can be generated using the CyClocksRT™ software.

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.
