xm104 daughtercard

Jump to solution

Hi, I have a ML605 board with the connectivity kit (XM-104 daughtercard).  Well, I need more SMA SERDES connectors and want to plug another XM104 board into the unused FMC connector (J63).  I noticed there was a XM-105 board specifically made up for the unused connector (J63), but it is basically for low speed debug.  Can another XM-104 board be connected to this connector?  Thanks.

 

Jeff

The FMC-XM104 module has multiple MGT connections

 

DP0 - SMA

DP1 - SMA

DP2 - SATA

DP3 - SATA

DP4:7 - CX4

DP8 -Loopback to self

DP9 - Loopback to self

 

The ML605 has the following MGT connections

 

FMC HPC - DP0 to DP7 connected.  DP8 & DP9 not connected

FMC LPC - DP0 connected. No other pairs supported by the specification

Yes, you can connector another XM104 to the other FMC slot.  However, this FMC is a LPC (Low Pin Count) type and there is only 1 MGT pair (DP0) available.

 

The good news is that DP0 is connected to the SMA connectors on the XM104.

so you're telling me that there are 2 pairs of TX/RX connectors on the FM104, but I only have access to 1 of them due to the wiring of the connector?
