Introduction
The XTS-FMC daughter card is designed to convert FPGA transceiver channels to SMA
connectors through a FPGA Mezzanine Card (FMC) interface. It is intended to allow users to
evaluate the performance of transceiver-based host boards with FMC interface specifically the
Stratix, Arria and Cyclone FPGA with integrated transceivers. Through the SMA connectors, the
FPGA transceiver signals can be easily connected to measurement instruments as well as allowing
gigabit data rate communication between multiple FPGAboards.
The XTS-FMC daughter card is the ideal platform to allow users to prototype and test their
high-speed interfaces quickly and easily in support of transceiver performance for jitter, protocol
compliance, and equalization.

In order to make the XTS-FMC daughter card and the FMC connector on the FMC card with
more secure hookup, the FMC side of the XTS-FMC daughter card has reserved two screw holes, as
shown in Figure 1-3. Users can use the screws, copper pillars, and nuts that come with the XTS-
FMC, to secure the XTS-FMC on the FPGA main board, as shown in Figure 1-4. Because
transceiver is mostly used for high-speed transmission applications, we strongly recommend that
users use the screws to secure the connection between the FPGA main board and the XTS-FMC
card.

This chapter illustrates the transcevier loopback reference design for the XTS-FMC card.

The transceiver test code is used to verify 4 transceiver channels of the FMC connector through
the XTS-FMC card and SMA cables. The transceiver channels are verified with PRBS31 test
pattern and with the data rates. For 5SGXEA7N2F45C2 Device of the TR5 board, the data rate of
the transceiver channel on the FMC connector runs at 12.5G bps.
Required Equipments
To enable an external loopback of transceiver channels, the following fixtures are required:
TR5 board and XTS-FMC card.
8 SMA cables for loopback the TX and RX port on the XTS-FMC card.
Demonstration Setups
The transceiver test code is available in the folder System CD\Demonstrations\TR5\demo_batch.
Here are the procedures to perform transceiver channel test:
1. Use the SMA cables to connect the TX ports and the RX ports on the XTS-FMC card
to implement the loopback function (See Figure 4-1, Figure 4-2). There are four channels in
total, note the difference between positive and negative ports.

2. Connect the XTS-FMC card to the FMC D or FMC A connector of the TR5 board.
Make sure the FMC connector between the two boards is locked with copper posts and screws
(See section 1.3).

3. Connect your TR5 board to your PC with a mini USB cable.
4. Connect Power to the TR5 board.
5. Copy the demo_batch folder (from System CD) to your local disk.
6. Power on the TR5 board.
7. Execute 'test.bat" in the demo_batch folder under your local disk.
8. The batch file will download .sof and .elf files, and start the test. The Nios-Terminal
as shown in Figure 4-3 will appear and choose “0”to test all the transceiver loopback test.

10. The test result will be displayed after the test time has elapsed (See Figure 4-5). It
should be noted that this test code will test all the transceivers of the FMC A and FMC D
connectors on the TR5 board (8 pairs of transceivers for each connector). Since XTS-FMC
card can only test 4 pairs of transceivers. So the test result will only show the first four
transceivers (0~3) of FMC A or FMC D are PASS or NG. Other transceiver test results can be
ignored.

This section describes the use of the XTS-FMC card to test the FPGA's transceiver loopback on
the HAN pilot platform. The basic operation is roughly the same as section 4.1, except that the
FPGA board is replaced. The following is a detailed test procedure.
Required Equipments
To enable an external loopback of transceiver channels, the following fixtures are required:
HAN Pilot Platform and XTS-FMC card.
8 SMA cables for loopback the TX and RX ports on the XTS-FMC card.
Demonstration Setups
The transceiver test code is available in the folder System CD\Demonstrations\HAN\XCVT
loopback. Here are the procedures to perform transceiver channel test:
1. Use the SMA cables to connect the TX ports and the RX ports on the XTS-FMC card
to implement the loopback function (See Figure 4-6).
2. Connect the XTS-FMC card to the FMC connector of the HAN Pilot Platform board.
Make sure the FMC connector between the two boards is locked with copper posts and screws
(See section 1.3).

8. The batch file will download .sof and .elf files, and start the test in the Nios-Terminal
as shown in Figure 4-7. When the menu option appears, you can choose 0 for starting test. The
program will automatically start the test and report the test results every five seconds until the
