Electrical Specifications
NOTES:
1.
Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2.
Crossing Voltage is defined as absolute voltage where rising edge of BCLK0 is equal to the falling edge of
BCLK1.
3.
Threshold Region is defined as a region entered about the crossing voltage in which the differential receiver
switches. It includes input threshold hysteresis.
4.
For Vin between 0 V and VIH.
5.
Cpad includes die capacitance only. No package parasitics are included.
6.
ΔV
CROSS is defined as the total variation of all crossing voltages as defined in note 2.
NOTES:
1.
Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2.
VIL is defined as the maximum voltage level at a receiving agent that will be interpreted as a logical low
value.
3.
VIH is defined as the minimum voltage level at a receiving agent that will be interpreted as a logical high
value.
4.
VIH and VOH may experience excursions above VCCP. However, input signal drivers must comply with the
signal quality specifications.
5.
This is the pull-down driver resistance.
6.
GTLREF should be generated from VCCP with a 1% tolerance resistor divider. Tolerance of resistor divider
decides the tolerance of GTLREF. The VCCP referred to in these specifications is the instantaneous VCCP.
7.
RTT is the on-die termination resistance measured at VOL of the AGTL+ output driver.
8.
Specified with on die RTT and RON are turned off.
9.
Cpad includes die capacitance only. No package parasitics are included.
10.
This spec applies to all AGTL+ signals except for PREQ#. RTT for PREQ# is between 1.5 kΩ to 6.0 kΩ.
