DESCRIPTION
Data pin for I2C circuitry 5V tolerant
Clock pin of I2C circuitry 5V tolerant
Ground pin.
Power pin for the 3V66 clocks.
Frequency select latch input pin / 3.3V 66.66MHz clock output.
Stops all PCICLKs besides the PCICLK_F clocks at logic 0 level, when input
low
Frequency select latch input pin / 3.3V 66.66MHz clock output / 48MHz
VCH clock output.
Ground pin.
Power pin for the 48MHz output.3.3V
48MHz clock output.
Frequency select latch input pin / 3.3V 48MHz clock output.
Frequency select pin.
Ground pin.
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.
3.3V LVTTL input for selection the current multiplier for CPU outputs
Complimentary clock of differential pair CPU outputs. These are current
mode outputs. External resistors are required for voltage bias.
True clock of differential pair CPU outputs. These are current mode
outputs. External resistors are required for voltage bias.
Supply for CPU clocks, 3.3V nominal
