3V66_4/VCH
OUT
66.66MHz clock output for AGP support. AGP-PCI should be aligned
with a skew window tolerance of 500ps.
VCH is 48MHz clock output for video controller hub.
Data pin for SMBus circuitry, 5V tolerant.
48MHz clock output.
48MHz clock output.
Ground pin.
Power pin for the 48MHz output.3.3V
This 3.3V LVTTL input is a level sensitive strobe used to determine
when latch inputs are valid and are ready to be sampled. This is an
active low input.
Power supply for SRC clocks, nominal 3.3V
Complement clock of differential pair for S-ATA support.
+/- 300ppm accuracy required.
True clock of differential pair for S-ATA support.
+/- 300ppm accuracy required.
Ground pin.

Supply for CPU clocks, 3.3V nominal
Stops all PCICLKs and SRC pair besides the PCICLK_F clocks at logic
0 level, when input low. PCI and SRC clocks can be set to
Free_Running through I2C. Internal pull-up of 150K nominal.
Stops all CPUCLK besides the free running clocks. Internal pull-up of
150K nominal
Frequency select pin, see Frequency table for functionality
This pin establishes the reference current for the differential current-
mode output pairs. This pin requires a fixed precision resistor tied to
ground in order to establish the appropriate current. 475 ohms is the
standard value.
Ground pin.
Ground pin for core.
3.3V power for the PLL core.
