DS90UB95x-Q1 Serializer Evaluation Module
The Texas Instruments DS90UB95x-Q1EVM evaluation module (EVM) is a functional board design for
evaluating the DS90UB953-Q1 FPD-Link III 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 serializer represents the next generation in FPD-III serializers and is 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 features
advanced data protection and diagnostic features to support ADAS and autonomous driving. Together
with a companion deserializer, the DS90UB953-Q1 delivers precise multi-camera sensor clock and sensor
synchronization. For a full list of device characteristics, refer to the DS90UB953-Q1 product folder.

2 Quick Start Guide
The quick start guide is intended to get the DS90UB95x-Q1EVM operational with the minimum amount of
information.
2.1 System Requirements
The major components of the DS90UB95x-Q1EVM are:
• DS90UB95xSerializer Board
• DS90UB953-DC1 Daughter Card
• 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.

3. Ensure jumpers and switches for DS90UB954-Q1EVM (or variant) are configured like shown in
Figure 5. See the DS90UB954-Q1EVM User's Guide (SNLU223) for further details.
Figure 5. DS90UB954-Q1EVM (or variant) With Jumpers Highlighted
4. Connect the DACAR coax cable with FAKRA connector to RX0p from the DS90UB954-Q1EVM (or
variant) to J16 of the DS90UB95x-Q1EVM
5. 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
6. Power the DS90UB954-Q1EVM (or variant) with 12 V through J1
7. Open ALP and assign the correct DS90UB953 and DS90UB954 (or variant) profiles to the appropriate
USB IDs
8. 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
9. Navigate back to the Scripting tab of the DS90UB954 (or variant) ALP profile and run the
ovt_1280_1080_30fps_REMOTE_RevE2_ID7a.py script to initialize the camera. 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 1920 and 1080, respectively.
10. 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 6. It is powered through the USB port of computer.
Figure 6. 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 3) 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 7 shows the USB2ANY
pinout with the I2C pins highlighted. Typically, jumper wires are used to connect these to the 953/954
EVMs.

WARNING
Directly interacting with devices either through register
modifications or calling device support library functions can effect
the performance and/or functionality of the user interface and may
even crash the ALP Framework application.
3.3.9.1 Example Functions
The following are Python functions commonly used to interact with FPD-Link devices.
3.3.9.1.1 Local I2C Reads/Writes
These functions will perform reads and writes only for the I2C assigned to board.devAddr, which by
default will be the detected address for the DS90UB954-Q1 (or variant).
board.ReadReg(Register Address , # of Bytes) OR board.ReadReg(Register Address)—I2C Read
Command
• Accepts both hex & decimal inputs
• Number of bytes will default to 1 if omitted
• Ex: board.ReadReg(0x00) will return the value in Register 0 for the local device
board.WriteReg(Register Address , Data) —I2C Write Command
• Accepts both hex & decimal inputs
• Ex: board.WriteReg(0x01, 0x01) will set Register 0 to have a value of 1
board.devAddr = [I2C Address]—Assigns I2C address to be used for board.ReadReg and
board.WriteReg commands
• Accepts both hex & decimal inputs
• Uses the 8-bit form of the I2C address
• Can be used to shorten read/write commands
• Ex: board.devAddress = 0x60 sets the board address to 0x60
3.3.9.1.2 General I2C Reads/Writes:
These I2C commands will work for any I2C address on the local bus and remote devices configured in the
slave ID and slave alias registers of the device. The 8-bit form of I2C addresses should be used.
board.ReadI2C(Device Address, Register Address , # of Bytes) OR board.ReadI2C(Device Address,
Register Address) —I2C Read Command
• Accepts both hex & decimal inputs
• Number of bytes will default to 1 if omitted
• Ex: board.ReadI2C(0x60, 0x00) will return the value in Register 0 for the device with address
0x60 (8-bit form)
board.WriteI2C(Device Address, Register Address , Data) —I2C Write Command
• Accepts both hex & decimal inputs
• Ex: board.WriteI2C(0x60, 0x01, 0x01) will set Register 1 of the device with address 0x60 (8-bit
form) to have a value of 1

3.3.9.1.3 I2C Reads/Writes with Multi-Byte Register Addresses
These I2C commands will work for any I2C address on the local bus and remote devices configured in the
slave ID and slave alias registers of the device. The 8-bit form of I2C addresses should be used.
board.ReadI2C(Device Address, Register Address Byte 2,[Register Address Byte 1, # of Bytes]) OR
board.ReadI2C(Device Address, Register Address Byte 2, [Register Address Byte 1]) —I2C
Read Command for devices with multi-byte register addresses
• Accepts both hex & decimal inputs
• Number of bytes will default to 1 if omitted
• Ex: board.ReadI2C(0x60, 0x30, [0x00]) will return the value in Register 0x3000 for the device
with address 0x60 (8-bit form)
board.WriteI2C(Device Address, Register Address Byte 2, [Register Address Byte 1, Data])—I2C
Write Command for devices with multi-byte register addresses
• Accepts both hex & decimal inputs
• Number of bytes will default to 1 if omitted
• • Ex: board.WriteI2C(0x60, 0x30, [0x01, 0x01]) will set Register 0x3000 of the device with
address 0x60 (8-bit form) to have a value of 1
