概要
Description
DS90UB949TRGCTQ1 is Texas Instruments’ 4-channel automotive FPD-Link III deserializer. It receives serialized video data from a matching FPD-Link III serializer (for example, DS90UB953/954 family) over a single coaxial or shielded twisted-pair cable and reconstructs four CSI-2/LVDS-style video streams for the host processor. The device includes clock/data recovery, a built‑in switch/decoder, and an I2C control interface for configuration and status monitoring. It’s designed for automotive camera networks (ADAS, surround-view, multi-camera sensing), allowing multiple cameras to share one high-speed link to a central MCU/SoC while saving wiring and simplifying system integration. The TRGCTQ1 suffix denotes the specific package/tape-and-reel variant of the device. In short: a multi-channel, automotive-grade deserializer that completes the FPD-Link III camera link with easy I2C control and broad temperature operation.
Features
DS90UB949TRGCTQ1 features (concise):
- Automotive-grade FPD-Link III serializer for camera links (MIPI CSI-2 to coax).
- MIPI CSI-2 input interface supporting multiple data lanes (up to 4 lanes).
- Single FPD-Link III coaxial output to a deserializer over long cable runs.
- Bi-directional link with VCP control on the same connection; I2C/SPI control from host.
- Supports common automotive video formats and frame rates (suitable for 1080p-class imaging).
- AEC-Q100 Grade 1 automotive qualification; operating range typically -40°C to 125°C.
- Low power with integrated regulators; suitable for typical automotive power rails.
- Compact package option (TRGCTQ1 variant) with robust ESD/EMI performance.
Note: exact lane-rate specifications and supported resolutions may vary by revision; refer to the current TI datasheet for precise numbers.
