2.9 PCIe Carrier Connectors
(continued)
The following is a simplified block diagram of the 7807 PCIe carrier.
2.9.4 XMC Connectors
The XMC site on the carrier provides two XMC connectors, designated
J15
and
J16
. These connectors follow the VITA 42.0 XMC Switched Mezzanine
Card Auxiliary Standard and VITA 42.3 XMC PCI Express Protocol Standard.
• J15 provides an x8 PCI Express link between the 71741 XMC module
and the 7807 PCIe bus. For 71741 Option 110 optical interface, the XMC
J15 MSDA and MSCL signals are used for control signals, through a
Philips PCA9535 I/O Port, to the Samtec FireFly control connectors ( J26
and J27 ). See Section 2.9.8 for the pin mapping of these signals.
• For 71741 Option 105 gigabit serial I/O, J16 provides separate data links
to the Samtec FireFly data connectors ( J24 , SER RX and J25 , SER TX ).
See Section 2.9.7 for the pin mapping for these connections.
2.9.5 PMC Connector (Option 104)
The 7807 carrier provides a 64−pin PMC connector, designated
J14
. The car−
rier routes 64 signals from J14 to a general−purpose connector, GPIO . See
Section 2.9.6 for the pin mapping of these connections.
Option 104 for the 71741 XMC provides 48 connections from 71741 FPGA
LVDS I/O pins to the PCIe carrier using
J14 . The Model 71741 Operating
Manual , 800.71741, describes the PMC P14 connector signals.
