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 I
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.
