Pin Description
The active polarity of a signal is defined using a suffix. Signals ending with an “N” are defined as being active, or asserted, when at a logic zero (low)
level. All other signals (including clocks, buses, and select lines) will be interpreted as being active, or asserted, when at a logic one (high) level. Differ-
ential signals end with a suffix “N” or “P.” The differential signal ending in “P” is the positive portion of the differential pair and the differential signal
ending in “N” is the negative portion of the differential pair.

Table 2 PCI Express Interface Pins (Part 1 of 2)
PCI Express Port 0 Serial Data Receive. Differential PCI Express receive pairs for
port 0. Port 0 is the upstream port.
PCI Express Port 0 Serial Data Transmit. Differential PCI Express transmit pairs for
port 0. Port 0 is the upstream port.
PCI Express Port 1 Serial Data Receive. Differential PCI Express receive pairs for
port 1. When port 0 is merged with port 1, these signals become port 0 receive pairs
for lanes 4 through 7.
PCI Express Port 1 Serial Data Transmit. Differential PCI Express transmit pairs for
port 1. When port 0 is merged with port 1, these signals become port 0 transmit pairs
for lanes 4 through 7.
PCI Express Port 2 Serial Data Receive. Differential PCI Express receive pairs for
port 2.
PCI Express Port 2 Serial Data Transmit. Differential PCI Express transmit pairs for
port 2.
PCI Express Port 3 Serial Data Receive. Differential PCI Express receive pairs for
port 3. When port 2 is merged with port 3, these signals become port 2 receive pairs
for lanes 4 through 7.
PCI Express Port 3 Serial Data Transmit. Differential PCI Express transmit pairs for
port 2. When port 2 is merged with port 3, these signals become port 2 transmit pairs
for lanes 4 through 7.
PCI Express Port 4 Serial Data Receive. Differential PCI Express receive pairs for
port 4.
PCI Express Port 4 Serial Data Transmit. Differential PCI Express transmit pairs for
port 4.
PCI Express Port 5 Serial Data Receive. Differential PCI Express receive pairs for
port 5. When port 4 is merged with port 5, these signals become port 4 receive pairs
for lanes 4 through 7.
PCI Express Port 5 Serial Data Transmit. Differential PCI Express transmit pairs for
port 5. When port 4 is merged with port 5, these signals become port 4 transmit pairs
for lanes 4 through 7.
PCI Express Port 6 Serial Data Receive. Differential PCI Express receive pairs for
port 6.
PCI Express Port 6 Serial Data Transmit. Differential PCI Express transmit pairs for
port 6.
PCI Express Port 7 Serial Data Receive. Differential PCI Express receive pairs for
port 7. When port 6 is merged with port 7, these signals become port 6 receive pairs
for lanes 4 through 7.
