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.

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 trans-
mit 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 trans-
mit 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 trans-
mit 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 trans-
mit pairs for port 3. 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 trans-
mit 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 trans-
mit 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 trans-
mit 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.
