VREF (Analog)
The VREF (GTL+ Reference Voltage) signal provides a DC level reference voltage for the GTL+
input buffers. A voltage divider should be used to divide V
CCT
by

/

. Resistor values of 1.00 kΩ
and 2.00 kΩ are recommended. Decouple the VREF signal with three 0.1-µF high-frequency
capacitors close to the processor.
