CY22392FXC集成电路（IC）的时钟发生器PLL频率合成器规格书PDF中文资料

Operation

The CY22392 is an upgrade to the existing CY2292. The new device has a wider frequency range, greater flexibility, improved performance, and incorporates many features that reduce PLL sensitivity to external system issues.

The device 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.
