DS90UB954-Q1EVM User's Guide
Chapter 1
SNLU223–December 2016
DS90UB954-Q1EVM User's Guide
1.1 Introduction
The Texas Instruments DS90UB954-Q1EVM evaluation module (EVM) is a functional board design for
evaluating the DS90UB954-Q1 FPD-Link III deserializer, which converts serialized camera data to MIPI
CSI-2 for processing. The MIPI CSI-2 output has four available lanes, and can be configured for either
four-lane output or replicated two-lane output. When paired with a DS90UB953-Q1 serializer, the
DS90UB954-Q1 receives data from imagers supporting 2MP/60fps and 4MP/30fps cameras as well as
satellite RADAR. The DS90UB954-Q1 also supports 1MP/60fps and 2MP/30fps imagers when coupled
with DS90UB913A/933 serializers. The DS90UB954-Q1EVM is configured for communication with a
DS90UB953-Q1 on channel 0 (RX0), and a DS90UB933-Q1 on channel 1 (RX1). The EVM has two
Rosenberger FAKRA connectors and configurable power-over-coax (POC) voltage for connecting the
camera modules (not included). FPD-Link III interfaces also includes a separate low latency bi-directional
control channel that conveys control information from an I2C port. General purpose I/O signals such as
those required for camera synchronization and functional safety features also make use of this bi-
directional control channel. There is an onboard MSP430 which functions as a USB2ANY bridge for
connecting a PC, which works with the Analog LaunchPAD GUI tool.
NOTE: The demo board is not intended for EMI testing. The demo board was designed for easy
accessibility to device pins with tap points for monitoring or applying signals, additional pads
for termination, and multiple connector options.

1.4.3 Power Over Coax Interface
The DS90UB954-Q1EVM offers two power over coax interfaces (POC) to connect cameras through a
coaxial cable with FAKRA connectors. Power is delivered on the same conductor that is used to transmit
video and control channel data between the host and the camera. By default, 5V power supply is applied
over the coax cable. Refer to Table 1-2 for other POC configurations.
NOTE: For port RX0, the POC network is configured for a DS90UB953, and for RX1 the POC
network is configured for a DS90UB933. Only use a serializer EVM with the correct POC
network. To use POC with two DS90UB953 or DS90UB933 EVM's, one of the POC networks
must be reworked. You may also open the POC circuit and power the serializer EVM directly
from another supply.
For power over coax (POC) on the EVM, the circuit uses a filter network as shown in Figure 1-5. The POC
network frequency response corresponds to the bandwidth compatible with DS90UB953-Q1 chipsets.

1.4.4 MIPI CSI-2 Output Signals
Provided on the DS90UB954-Q1EVM, J5 and J6 are Samtec QSH-type connectors that can be mated
with a matching QTH type connector. This Samtec connector provides a means to route CSI-2 signals out
of the DS90UB954-Q1. The J5 connector is on the top side of the EVM for accessability, and the J6
connector is on the bottom for mating with a TDAx evaluation kit. The signals to the connectors are the
same, including access to I2C and other miscellaneous GPIO signals. Only one connector should be used
at a time. If the J6 connector on the bottom is to be used, populate the zero ohm resistors on the bottom
of the board which extened the traces to the J6 connector. The mating connector part number is QTH-
020-01-H-D-DP-A.
There are third party solutions like the HDR-128291-XX breakout board from Samtec which can be used.
The HDR- 128291-XX is a breakout board with a mating connector to J5 or J6, providing access to each
pin through standard SMA male connectors. More info on this breakout board can be obtained from
Samtec website. Another third party option is the ZX100 by Zebax Technologies. More information on this
board can be obtained from Zebax website.

1.6 Typical Connection and Test Equipment
The following is a list of typical test equipment that may be used to monitor the MIPI CSI-2 signals from
the DS90UB96X-Q1:
1. Logic Analyzer
2. Any SCOPE with a bandwidth of at least 4 GHz for observing differential signals.
3. UNH-IOL MIPI D-PHY Reference Termination Board (RTB)
4. UNH-IOL MIPI D-PHY/CSI/DSI Probing Board
5. UNH-IOL CSIGUI Tool
1.7 Termination Device
A termination device is required in order to properly monitor and measure the transmission of the MIPI
DPHY signals. The termination device should support the change of signals as it switches between LP
and HS modes. This can be provided by either a CSI-2 receiver or a dedicated dynamic termination board.
The recommended termination board is the UNH-IOL MIPI D-PHY Reference Termination Board (RTB).
1.8 Typical Test Setup
Figure 1-6 and Figure 1-7 illustrate the typical test setups used to measure and evaluate DS90UB96X-Q1.
