NOTES:
1. The typical transition point between V
V
±100 mV respectively, for a system bus agent using on-board termination. V
REF
mV respectively, for a system bus agent using on-die termination.
2. Parameter measured into a 22.5 ohm resistor to 1.2V. Minimum V
3. Calculated using off-die termination through two 45 ohm ±1% resistors in parallel.
4. Calculated using on-die termination to a 45 ±15% resistor measured at V
5. At 1.2V ±1.5%. V
6. Total of I/O buffer with ESD structure and processor parasitics if applicable. Capacitance values guaranteed by design for all
AGTL+ buffers.
