DS90UB95x-Q1 Serializer Evaluation Module
Ankur Verma, Cole Macias
ABSTRACT
The Texas Instruments DS90UB95x-Q1EVM evaluation module (EVM) is a functional board design for
evaluating the DS90UB953-Q1 FPD-Link III serializer and the TSER953 V3Link serializer. This document
provides necessary details for the evaluation such as a brief product overview, quick-start guide, troubleshooting
section, schematics, and printed-circuit board (PCB) layout details, and bill of materials (BOM).
The DS90UB953-Q1 and TSER953 serializers represent the next generation in FPD-Link III and V3Link
serializers and are designed to support high-speed raw data sensors including 2-MP imagers at 60 fps, as
well as 4-MP, 30-fps cameras, satellite RADAR, LIDAR, and time-of-flight (ToF) sensors. The chip delivers a
4-Gbps+ forward channel and an ultra-low latency, 50-Mbps bidirectional control channel. The chip also supports
power over a single coax (PoC) or shielded twisted-pair (STP) cable and connector. The DS90UB953-Q1 and
TSER953 feature advanced data protection and diagnostic features to support ADAS, autonomous driving, and
industrial and medical imaging applications. Together with a companion deserializer, the chip delivers precise
multi-camera sensor clock and sensor synchronization. For a full list of device characteristics, refer to the
DS90UB953-Q1 and TSER953 product folders.

2 Quick Start Guide
The quick start guide is intended to get the DS90UB95x-Q1EVM operational with the minimum amount of
information. See Section 3.5 in the troubleshooting section for in-depth, step-by-step instructions.
2.1 System Requirements
The major components of the DS90UB95x-Q1EVM are:
• DS90UB95xSerializer Board
• On-board Power-over-Coax (PoC) interface
• FAKRA connector for digital video, power, and diagnostics
• On-board I2C programming interface
To demonstrate, TI recommends the following (not included):
• DS90UB954-Q1EVM (or variant)
• One DACAR/FAKRA coax cable
• DC power supply for DS90UB954-Q1EVM (or variant) only
• Power supply cables: for example, banana to coax, banana to grabber, and so forth.
• Two male USB-to-mini USB cables
• USB2ANY or an Aardvark I2C/SPI Host Adapter
• Analog LaunchPAD software (download Analog Launch PAD from TI.com (a myTI Login required). Steps for
installation can be found in Section 3.3). This software is not required if an external ECU is used.

2. Ensure jumpers and switches for DS90UB954-Q1EVM (or variant) are configured like shown in Figure 2-4.
See the DS90UB954-Q1EVM User's Guide (SNLU223) for further details.
Figure 2-4. DS90UB954-Q1EVM (or variant) With Jumpers Highlighted
3. Connect the DACAR coax cable with FAKRA connector to RX0p from the DS90UB954-Q1EVM (or variant)
to J16 of the DS90UB95x-Q1EVM
4. Connect a mini USB to J2 on the DS90UB954-Q1EVM (or variant) and J9 on the DS90UB95x-Q1EVM to a
device with Analog LaunchPAD (ALP) software installed
5. Power the DS90UB954-Q1EVM (or variant) with 12 V through J1
6. Open ALP and assign the correct DS90UB953 and DS90UB954 (or variant) profiles to the appropriate USB
IDs
7. The DS90UB95x-Q1EVM and DS90UB954-Q1EVM (or variant) should now be linked and have established
connection. Go to information tab on the DS90UB954 (or variant) device window and confirm that Pass Sts
displays Pass and Linked has the appropriate frequency displayed. Also check if Pass and Lock LEDs are lit
8. Navigate back to the Scripting tab of the DS90UB954 (or variant) ALP profile and run the
953to954_patgen_YUV_1920x1080p-4Lanes-Working.py script to initialize a pattern generation test from
the 953. The script may be found by clicking on the "Run PreDef Script" button. If the DS90UB954-Q1 (or
variant) is not using an I2C address of 0x7A (8-bit form), the script should be modified to use the correct I2C
address. Go back to the information tab of the DS90UB954-Q1 (or variant) and confirm the horizontal and
vertical parameters read 3820 bytes and 1080 lines, respectively.
9. If there are any problems, consult Section 3.5 for an in-depth step-by-step guide to enable the pass and lock
2.5 Use With DS90UB935-Q1
The only modification required to use the DS90UB95x-Q1EVM to evaluate the DS90UB935-Q1 is to exchange
the DS90UB953-Q1 with the DS90UB935-Q1. No additional rework is required.

3 Troubleshooting
3.1 Default Addresses
The default 9-bit I2C address of DS90UB95xis set to 0x30 (011 0000) using suitable resistor divider on ID[x] pin.
Also, 8-bit I2C address of DS90UB954 (or variant) is set to 0x7A (0111 1010) using suitable resistor dividers on
pins IDX[0] and IDX[1].
3.2 USB2ANY
The USB2ANY is required to work with any interactive GUI over I2C, such as ALP (Analog LaunchPAD).
Download and install ALP from: http://www.ti.com/tool/ALP.
The USB2ANY is shown in Figure 3-1. It is powered through the USB port of computer.
Figure 3-1. USB2ANY
There are two methods to use the USB2ANY to communicate with the 953/954 EVMs. The first method is to
simply connect the USB to Mini-USB cable to the USB port of your computer and the Mini-USB ports on the
EVMs, J9 for the 953 EVM (see Figure 2-2) and J2 on the 954 EVM. If using the first method, skip to Section 3.3.
The second method is to use the pinout of the USB2ANY. Figure 3-2 shows the USB2ANY pinout with the I2C
pins highlighted. Typically, jumper wires are used to connect these to the 953/954 EVMs.

Figure 3-2. I2C Pinout of USB2ANY Connector
On the DS90UB954-Q1EVM (or variant), connect the other ends of the corresponding wires to pins 2, 3, and 4 of
J25 labeled SCL, SDA, and GND, respectively.
On the DS90UB95x-Q1EVM, connect the other ends of the corresponding wires to pins 1, 2, and 3 of J5 for 1.8
V, or J6 for 3.3 V labeled SCL, SDA, and GND, respectively. Note that these voltages refer to the pullup voltage
used in I2C communication. As a result, check the mode of the I2C adapter before plugging in to the adapter.
Connecting the Mini USB to USB cable from the port of the USB2ANY to the computer should allow ALP to
communicate with the EVM. However, if the EVMs are configured to have 1.8 V I2C signal levels (see J5 on
the 953 EVM and J16 on the 954 EVM), the USB2ANY must be configured to support the 1.8 V required
by the DS90UB95x-Q1EVM and DS90UB954-Q1EVM (or variant). To do this, the user must navigate to the
USB2ANY.py script and change the code. The path to the file is given below:
SPACER
C:\Program Files (x86)\Texas Instruments\Analog LaunchPAD
v1.56.0010\Drivers\i2c_controllers\usb2any\python
SPACER
Once the usb2any_lib.py script is found, open the script in a text editing program (for example, Notepad,
Wordpad, Notepad++, and so forth) and replace Line 61 from:
SPACER
self.usb2anydll.u2aI2C_Control(self.u2ahandle,1,0,0)
SPACER
To the following:
SPACER
self.usb2anydll.u2aI2C_Control(self.u2ahandle,1,0,1)
self.usb2anydll.u2aPower_WriteControl(self.u2ahandle,1,0)
SPACER
Save the script, close the program, and ALP will now recognize the connection from the board to the USB2ANY.
