Ground: Normally 0 volts. See Figure 11 for Recommended Power Supply Filtering.

Analog Power Supply: Normally 3.3 volts. Used to provide a clean supply line for the Clock and Data

Recovery (CDR) circuit. See Figure 11 for Recommended Power Supply Filtering.

High Speed Supply: Normally 3.3 volts. Used only for high-speed outputs (TO_NODE[n]). See Figure 11 for

Recommended Power Supply Filtering.

Logic Power Supply: Normally 3.3 volts. Used for internal logic. See Figure 11 for Recommended Power

Supply Filtering.

HDMP-0482 Absolute Maximum Ratings

Ta=25° C, except as specified. Operation in excess of any of these conditions may result in permanent

damage to this device. Ta refers to the ambient temperature for the board upon which the parametric

measurements were taken.
