USER MANUAL
1.0 Introduction
The UT65CML8X8FD-EVB Evaluation Board provides a comprehensive platform for evaluating the UT65CML8X8FD
3.125 Gbps Crosspoint Switch (XPS). The XPS is configured via the internal registers as specified in the register map
section of the data sheet. Internal registers are configured via the XPS SPI port. A Software (SW) Graphical User
Interface (GUI) is provided with the UT65CML8X8FD-EVB to facilitate setup of the XPS device. Users can specify
high-speed signal routing paths, input receiver (RX) equalization (EQ), output transmitter (TX) amplitude, and all
other User-configurable operating parameters through the SW GUI. This User Guide serves to provide setup and
operation of the UT65CML8X8FD-EVB, including both Hardware (HW) and Software (SW).

USER MANUAL
8.0 Operating Instructions
8a) Hardware (HW) Setup
XPS functional overview: Figures 5a, 5b show the functional diagram of the UT65CML8X8FD-EVB configuration.
Figure 5a shows all possible XPS switch connections by device programming using the SW GUI. Figure 5b shows
the XPS default switch connections at power-up.
In all cases, Port N RX Channel 0 connects only to Port N TX Channel 0, Port N RX Channel 1 only to Port N TX
Channel 1, Port N RX Channel 2 only to Port N TX Channel 2, and Port N RX Channel 3 only to Port N TX Channel 3.
This architecture is consistent with XPS use in SpaceVPX/VITA 78-based systems as an A/B Redundancy RapidIO /
XAUI port switch.
The piece-parts for only Channel 1 for all Ports 0-3 are installed with a) SMA Jacks, and b) AC-coupling capacitors.
Additional channels may be populated with these piece-parts depending on user system configuration and
requirements. Part numbers, manufacturers, and quantities are given in the Bill of Materials (BoM).

USER MANUAL
Figure 5b: Evaluation Board Test Configuration –Default XPS Connections
Configure Hardware: Connect power, SPI interface, and high-speed signal cables, as shown in Figures 1, 4, 6. The
UT65CML8X8FD-EVB can be oriented either horizontally (as shown), or vertically to facilitate test equipment setup.
This flexible orientation is facilitated by having all high-speed RX inputs on the bottom side and all high-speed TX
outputs on the top side of the EVB. See Figures 2, 3. Right angle SMA adapters are recommended for horizontal
EVB orientation. See Figure 6.
Connect NI USB-6501 USB-to-SPI Interface Device (see Figure 7) to a) Windows PC Computer via USB AB 2.0
cable, and b) EVB Master SPI port via custom interface cable (see Figures 7, 8). For correct orientation of the
connector to the header pins, the white wire is connected to VDD EXT and the black wire is connected to GND. See
Figures 1, 2, 7, 8.
Now connect and configure power supplies to the EVB. The recommended initial configuration is as follows:
VDD=VDDRX=VDDTX=1.20V and VDD_25=2.5V. Power sequencing is not critical to operation of the XPS,
however, we recommend core power (VDD) to power-up before, or simultaneously with I/O power (VDDRX,
VDDTX) and SPI port power (VDD_25).

8b) Software (SW) Setup
The CAES UT65CML8X8FD-EVB XPS Evaluation Board Graphical User Interface (GUI) Software (SW) is required to
configure the XPS IC via the internal registers. See register description in the Register Map section of the data
sheet.
Installation instructions: Follow the installation instructions provided at website link to XPS SW GUI. Copy the
indicated files to the Windows PC computer that is intended to operate the GUI. Run the installer program. After a
successful GUI installation the GUI executable file “CAES XPS.exe” will be present in the run directory where the GUI
SW was installed. Double-click on this executable file to start the GUI. Click on the “Run” button as shown in
Figure 9. Set the PC device port for the NI USB-6501 USB-to-SPI Interface Device.
Once the GUI is operating, configure the XPS registers as required for your test configuration. Note that the XPS IC
will initialize in the default setting, per the Register Map, upon power-up. Always click on the “Run” button after re-
configuring the GUI settings to insure that the registers are updated with new data.
The recommended initial Receiver (RX) Equalization (EQ) setting is b’510101, or 0x15. This is different than the
power-up default setting of b’501000, or 0x08. See Table 10: SPI Port Register Map, p.18-19 of the data sheet.
The register names: EQ_<3:0>_<3:0>[4:0] and numbers: 0x04-0D are listed in the Register Map.
