General Description
The CY22388 family of devices has an Analog VCXO (Voltage Controlled Crystal Oscillator), 4 PLLs, up to 8 clock outputs and frequency selection capabilities. The frequency selects do not modify any PLL frequency. Instead they allow the user to choose between up to 8 different output divider selections depending on the clock and package configuration. This is illustrated in the following Frequency Selection tables and Functional Block Diagram.
