一般的な説明

Four Configurable PLLs

The CY2545 and CY2547 have four I2C programmable PLLs available to generate output frequencies ranging from 3 to 166 MHz. The advantage of having four PLLs is that a single device generates up to four independent frequencies from a single crystal. Two sets of frequencies for each PLL can be programmed. This enables in system frequency switching using multifunction frequency select pin, FS.

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.
