Functional Description
Power management options (Shutdown, OE, Suspend)
The CY22393, CY22394, and CY22395 are a family of parts
Configurable crystal drive strength
designed as upgrades to the existing CY22392 device. These
Frequency select through three external LVTTL inputs
parts have similar performance to the CY22392, but provide
advanced features to meet the needs of more demanding
3.3 V operation
applications.
16-pin TSSOP package
The clock family has three PLLs which, when combined with the
reference, allow up to four independent frequencies to be output
CyClocksRT software support
on up to six pins. These three PLLs are completely
programmable.
The CY223931 is the CY22393 with NiPdAu lead finish.
