TDES954 V3Link Deserializer Dual Hub

Texas Instruments' TDES954 is a versatile dual deserializer hub that can receive serialized sensor data from one or two independent sources through a V³Link interface. When paired with the TSER953 serializer, the TDES954 receives data from imagers, supporting 2 MP/60 fps and 4 MP/30 fps cameras, as well as satellite RADAR and other sensors such as ToF and LIDAR. The data is received and aggregated into a MIPI CSI-2 compliant output for interconnection to a downstream processor. For sensors with DVP-mode serializers, the TDES954 receives and aggregates data from one or two sensors including full HD 1,080 pixels 2 MP/60 fps imager sensors. When configuring the CSI-2 interface for 2-lane operations, a duplicate MIPI CSI-2 clock lane is available to provide a replicated output. The replication mode creates two copies of the aggregated video stream for data logging and parallel processing.

The TDES954 and partner TSER953 chipset is designed to receive data across 50 Ω single-ended coaxial or 100 Ω differential shielded twisted-pair (STP) cables. The deserializer hub is ideal for power-over-coax (PoC) applications and the receiving equalizer automatically adapts to compensate for cable loss characteristics with no additional programming required including cable degradation over time. Each V3Link interface includes a separate low latency bidirectional control channel (BCC) that continuously conveys I²C, GPIO, and other control information. The GPIO signals purposed for sensor synchronization and diagnostic features also make use of the BCC.
