CY28322-2 66-MHz input to buffered 66BUFF and PCI or 66-MHz clock from internal VCO 66-MHz buffered outputs from 66Input or 66-MHz clocks from internal VCO 33 MHz clocks divided down from 66Input or divided down from 3V66 Fixed 48-MHz clock output Fixed 48-MHz clock output Special 3.3V 3-level input for Mode selection 3.3V LVTTL inputs for CPU frequency se.

Features

• Compliant with Intel CK-Titan and CK-408 clock synthesizer/driver specifications
• Multiple output clocks at different frequencies — Two pairs of differential CPU outputs, up to 200 MHz — Nine synchronous PCI clocks, three free-running — Six 3V66 clocks — Two 48-MHz clocks — One reference clock at 14.318 MHz — One VCH clock
• Spread Spectrum clocking (down spread)
• Power-down features (PCI_STOP#, CPU_STOP# PWR_DWN#)
• 48-pin TSSOP package Enables reduction of EMI and overall system cost Enables ACPI-compliant designs  Benefits Supports next generation Pentium processors using differentia.
