General Description

4 Configurable PLLs The CY2542 is a four-PLL clock generator IC. It can be used to generate four independent output frequencies ranging from 3 to 50 MHz (for 1.5 V/1.8 V output voltage) or 3-166 MHz (for 2.5 V/3.0 V/3.3 V output voltage) from a single crystal or a reference clock. 2-wire Serial Interface Programming The CY2542 have a 2-wire serial interface that programs the configuration memory array to synthesize output frequencies by programmable output divider, spread characteristics, and drive strength. 2-wire Serial Interface can also be used for in-system control of these programmable features.

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.
