ABSTRACT
The Texas Instruments DS90UB954-Q1EVM evaluation modules (EVM) are functional board designs for
evaluating the DS90UB954-Q1 FPD-Link III and TDES954 V
3
Link deserializers, which convert serialized camera
data to MIPI CSI-2 for processing. The MIPI CSI-2 output has four available DPHY data lanes, which can be
configured for either four-lane output or replicated two-lane output. When paired with a compatible serializer, the
deserializer can receive data from imager(s) supporting cameras as well as satellite RADAR. The DS90UB954-
Q1 also supports DS90UB913A/933 serializers.
Some variants are single channel. For these variants, ignore references to RX1. Some references are made to
serializer backward compatibility. Refer to the product datasheet for serializer compatibility.
The DS90UB954-Q1EVM is configured for communication with the DS90UB953-Q1 and TSER953 on channel
0 (RX0), and 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
and V
3
Link interfaces also include a separate low latency bidirectional control channel that conveys control
information from an I
2
C port. General purpose I/O signals, such as those required for camera synchronization
and functional safety features, also make use of this bidirectional control channel to program registers in the
DS90UB954-Q1 and TDES954, as well as the connected serializer and any remote I2C connected devices.
There is an onboard MSP430 which functions as a USB2ANY bridge for interfacing with a PC for evaluation. The
USB2ANY interfaces with the
Analog LaunchPAD GUI tool.
