General Description
The ICS9160-03 generates all clocks required for high speed RISC microprocessor systems based on the PowerPC 603 and 604. Five different frequency multiplying factors are selectable and offer smooth frequency transitions. BCLK signals are synchronous to PCLK and operate at PCLK/2 for optimum synchronous PCI bus performance. The multiplying and ratio factors can be customed for specific applications.

Features
• Generates four processor and seven synchronous bus clocks plus graphic, floppy, keyboard and reference clocks
• Selectable 33.3/50/60/66.6/80 MHz PCLKs
• ±150ps maximum PowerPC PLL in-band jitter
• All synchronous clocks skew matched to ±250ps
• Individual or group stop-clock control
• Power-down modes minimize standby current
• Custom configurations available
• 3.0V - 5.5 supply range
• 32-pin SOIC package
