0218D—10/06/05
Frequency Generator for Pentium
TM Based Systems
Pin Configuration
Twelve selectable CPU clocks operate up to 83.3MHz
Maximum CPU jitter of ± 200ps
Six BUS clocks support sync or async bus operation
250ps skew window for CPU outputs, 500ps skew
window for BUS outputs
CPU clocks BUS clocks skew 1-4ns (CPU early)
Integrated buffer outputs drive up to 30pF loads
3.0V - 3.7V supply range, CPU(1:6) outputs 2.5V(2.375-
2.62V) VDD option
32-pin SOIC/SOJ package
Logic inputs latched at Power-On for frequency selection
saving pins as Input/Output
48 MHz clock for USB support and 24 MHz clock for FD.
32-Pin SOIC/SOJ
VDD Groups:
VDD = X1, X2, REF/BSEL
VDDC1 = CPU1-6
VDDC2 = CPU7-12 & PLL Core
VDDB = BUS1-6
VDDF = 48/24 MHz
