Notes:
1. CMOS signals have a reference voltage (Vref) equal to VCCIO/2.
2. GTL signals have a reference voltage (Vref) equal to VCCIO*(2/3).
3. All single-ended buffer types, including inputs, outputs and input/outputs, include an on-die pull up resistor
between 4 kOhms and 8.7 kOhms. Recommended values for external pull-downs on the inputs and input/
output signals must meet the V
il
specification for that buffer.
