Electrical Specifications
Notes:
1.
Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2.
The V
CCIO
referred to in these specifications refers to instantaneous V
CCIO
.
3.
For V
IN
between “0” V and V
CCIO
. Measured when the driver is tristated.
4.
V
IH
and V
OH
may experience excursions above
V
CCIO. However, input signal drivers must comply with the
signal quality specifications.
Notes:
1.
Refer to the PCI Express Base Specification for more details.
2.
V
TX-AC-CM-PP
and V
TX-AC-CM-P
are defined in the PCI Express Base Specification. Measurement is made over
at least 10^
6
UI.
3.
As measured with compliance test load. Defined as 2*|V
TXD+
– V
TXD-
|.
4.
COMP resistance must be provided on the system board with 1% resistors.
5.
PEG_ICOMPO, PEG_COMPI, PEG_RCOMPO are the same resistor.
6.
RMS value.
7.
Measured at Rx pins into a pair of 50-terminations into ground. Common mode peak voltage is defined by
the expression: max{|(Vd+ - Vd-) - V-CMDC|}.
8.
DC impedance limits are needed to ensure Receiver detect.
9.
The Rx DC Common Mode Impedance must be present when the Receiver terminations are first enabled to
ensure that the Receiver Detect occurs properly. Compensation of this impedance can start immediately
and the 15 Rx Common Mode Impedance (constrained by RLRX-CM to 50 ±20%) must be within the
specified range by the time Detect is entered.
10. Low impedance defined during signaling. Parameter is captured for 5.0 GHz by RLTX-DIFF.
11. These are pre-silicon estimates and are subject to change.
