Operation
The CY22381 is an upgrade to the existing CY2081. 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 that allow each output to operate at an independent frequencies. These three PLLs are completely programmable.
The CY223811 is the CY22381 with NiPdAu lead finish.
