3.3V tolerant input for CPU frequency selection. Refer to input electrical
characteristics for Vil_FS and Vih_FS values./ 3.3V PCI free running clock
output.
Power pin for the 48MHz output.3.3V
Latched select input for 24/48MHz output / 24/48MHz clock output.
1=24MHz, 0 = 48MHz.
48.00MHz USB clock
Ground pin.
True clock of differential pair for 96.00MHz DOT clock.
Complement clock of differential pair for 96.00MHz DOT clock.
Vtt_PwrGd# is an active low input used to determine when latched inputs
are ready to be sampled. PD is an asynchronous active high input pin
used to put the device into a low power state. The internal clocks, PLLs
and the crystal oscillator are stopped.
