PIN NUMBER 1 PIN NAME CPUCLKC0 TYPE OUT DESCRIPTION "Complementary" clocks of differential pair CPU outputs. These clocks are 180° out of phase with SDRAM clocks. These open drain outputs need an external 1.5V pull-up. "True" clocks of differential pair CPU outputs. These clocks are in phase with SDRAM clocks. These open drain outputs need an external 1.5V .
• 1 - CPU clocks @ 2.5V
• 1 - Pair of differential CPU clocks @ 3.3V
• 9 - SDRAM @ 3.3V
• 7 - PCI @3.3V
• 1 - 48MHz, @3.3V
• 1 - 24/48MHz @ 3.3V
• 3 - REF @3.3V, (selectable strength) through I2C Features:
• Programmable ouput frequency
• Programmable ouput rise/fall time
• Programmable CPU, SDRAM, and PCI skew
• Real time system reset output
• Spread spectrum for EMI control typically by 7dB to 8dB, with programmable spread percentage
• Watchdog timer technology to reset system if over-clocking causes malfunction
• Uses external 14.318MHz crystal Skew Specifications:
• CPU - CPU: <250ps
• PC.
