W305B - Frequency Controller with System Recovery for Intel® Integrated Core Logic - SPECTRALINEAR 数据手册 ( 数据表 )

Features
• Single chip FTG solution for Intel Solano/810E/810
• 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 simplify system BIOS development
• Vendor ID and Revision ID support
• Programmable drive strength for SDRAM and PCI
   output clocks
• Programmable output skew between CPU, AGP, PCI
   and SDRAM
• Maximized EMI suppression using Cypress’s Spread
   Spectrum Technology
• Low jitter and tightly controlled clock skew
• Two copies of CPU clock
• Thirteen copies of SDRAM clock
• Eight copies of PCI clock
• One copy of synchronous APIC clock
• Three copies of 66-MHz outputs
• Three copies of 48-MHz outputs
• One copy of double strength 14.31818-MHz reference
   clock
• One RESET output for system recovery
• SMBus interface for turning off unused clocks
