Texas Instruments DS90UB954-Q1
Dual 2MP FPD-Link III Deserializer With CSI-2 Outputs for 2MP/60fps Cameras and RADAR
Overview

| IC revision | snlu223 |
Description
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 up to 2MP/60fps and 4MP/30fps cameras as well as satellite RADAR. The DS90UB954-Q1 also supports up to 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 to program registers in the DS90UB954-Q1 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.
