Texas Instruments TDES954 4.16Gbps V3Link Deserializer Hub
Texas Instruments TDES954 4.16Gbps V3Link Deserializer Hub is a versatile dual deserializer hub capable of receiving serialized sensor data from one or two independent sources through a V3Link interface. When paired with a TSER953 serializer, the TDES954 receives data from imagers, supporting 2MP/60fps and 4MP/30fps cameras, as well as satellite RADAR and other sensors such as ToF and LIDAR. Data is received and aggregated into a MIPI CSI-2 compliant output for interconnecting to a downstream processor. For sensors with DVP Mode serializers, the TDES954 receives and aggregates data from one or two sensors, including Full HD 1080p 2MP 60/fps imager sensors. When configuring the CSI-2 interface for 2-lane operation, a duplicate MIPI CSI-2 clock lane is available to provide a replicated output. Replication mode creates two copies of the aggregated video stream for data logging and parallel processing.
The Texas Instruments TDES954 and partner TSER953 chipset is designed to receive data across either 50Ω single-ended coaxial or 100Ω differential STP cables. The deserializer hub is ideal for Power-over-Coax applications, and the receive 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. GPIO signals purposed for sensor synchronization and diagnostic features also make use of the BCC.
