System clock frequencies of 66.6 MHz and 100 MHz are supported. Split supplies of 3.3V and 2.5V are used. The 3.3V power supply powers everything except the CPU clock. The 2.5V power supply is usedtopowertheCPUCLKoutputs.2.5VsignalingfollowsJEDEC standard 8-X. Power sequencing of the 3.3V and 2.5V supplies is not required. An asynchronous PWR_DWN# signal may be used to orderly power down (or up) the system. CPU and PCI clocks may also be stopped by the CPU_STOP# and PCI_STOP# signals. The PI6C103 contains the Spread Spectrum function for only those clocks that synchronize to the CPU clocks (CPU and PCI clocks). 28-Pin H, L Features Two copies of CPU clock 100 MHz or 66.6 MHz operation Six copies of PCI clock, (synchronous with CPU clock) Two copies of REF clock @ 14.31818 MHz One copy of 48 MHz One copy of selectable 48/24 MHz Power management control input pins Isolated core VDD, VSS pins for noise reduction 28-pin SSOP (H) and TSSOP (L) packages REF [0:1] PCICLK [1:5] CPUCLK [0:1] REF OSC CPU_STOP# 2 2 5 PCICLK_F 48 MHz 48/24 MHz PCI_STOP# DIV ÷2 PLL1 XTAL_OUT XTAL_IN SEL100/66# SEL48# SPREAD# PWR_DWN# MUX PLL2 TS# SSC Options: Device 66MHz 100MHz PI6C103 0.67% 0.65% PI6C103-05 1.35% 1.35% PI6C103-06 1.79% 1.79% |
