Vx
Digital Core Power Supply (1.3V).
The supply pin inturn supplies the main
XTAL Oscillator/PLL (1.3V) . A higher
decoupling capacitor is therefore
recommended to the VSS pin for better
noise immunity.

Vx
Digital Power Supply for Oscillator,
LVDSH and A2 pads (3.3V).
The supply pin inturn supplies the main
XTAL Oscillator/PLL (3.3V) . A higher
decoupling capacitor is therefore
recommended to the VSS pin for better
noise immunity.
