CY28323 FTG

Crystal Connection or External Reference Frequency Input: This pin has dual functions. It can be used as an external 14.318-MHz crystal connection or as an external reference frequency input. Crystal Connection: Connection for an external 14.318-MHz crystal. If using an external reference, this pin must be left unconnected. Reference Clock 0/Current Multipli.

Features


• Compatible to Intel® CK-Titan & CK-408 Clock Synthesizer/Driver Specifications
• System frequency synthesizer for Intel Brookdale 845 and Brookdale - G Pentium® 4 Chipsets
• Programmable clock output frequency with less than 1 MHz increment
• Integrated fail-safe Watchdog timer for system recovery
• Automatically switch to HW selected or SW programmed clock frequency when watchdog timer time-out
• Capable of generating system RESET after a Watchdog timer time-out occurs or a change in output frequency via SMBus interface
• Support SMBus byte read/write and block read/ write operations to si.
