Electrical Characteristics

Inputs and Outputs

Parameter Minimum Maximum Units
Input high voltage 2.0 Vcc + 0.5 V
Input low voltage −0.5 0.8 V
Output high voltage 2.4 — V
Output low voltage — 0.5 V
Input high current — 10 µA
Input low current — −10 µA
Non-PCI output high current −4, −8 or −16 — mA
Non-PCI output low current 4, 8 or 16 — mA

Output drive depends on the pin. The PDF leaves maximum supply current blank.

Clocks and Supply

Parameter Minimum Maximum Units
XtalIn 14.300 14.336 MHz
Xtal1 high / low fraction 40 60 %
DirectMClk 0 170 MHz
DirectPClk 0 170 MHz
VDD / VDDA 3.135 3.465 V
V5V 4.75 5.25 V

XtalIn is not five-volt tolerant. Use an LVTTL-level input when not using a crystal. The source recommends an independent 3.3 V analog regulator for DAC and PLL supplies.
