TDES954RGZT

Overview

The TDES954RGZT is a dual deserializer hub from Texas Instruments designed for high-speed, high-resolution cameras and sensors. It aggregates serialized sensor data from one or two independent sources via the V3Link interface. The device supports MIPI CSI-2 compliant outputs with scalable data rates up to 1.6 Gbps per lane across four data lanes. It operates within a temperature range of –20°C to +85°C and features adaptive receive equalization for coaxial or STP cables. Key specifications include I2C support up to 1 Mbps, flexible GPIOs, and compatibility with TSER953 serializers.

Feature Summary

• Dual deserializer hub aggregating one or two active sensors over V3Link interface
• MIPI DPHY version 1.2 / CSI-2 version 1.3 compliant output ports
• Adaptive receive equalization for single-ended coaxial or shielded twisted-pair cables
• Ultra-low data and control path latency with line fault detection

Applications

• Appliances
• Video Surveillance
• Industrial Robots
• Machine Vision
• Patient Monitoring and Diagnostics

Procurement Notes

Verify the specific ordering suffix (e.g., RGZR vs. RGZT) against the manufacturer's official orderable addendum to ensure correct packaging configuration. Confirm that the voltage supply requirements match the system design, particularly regarding the VDD_SEL pin configuration for internal or external LDO regulation. Ensure all power rails are sequenced correctly according to the datasheet recommendations before enabling the device.

Selection Notes

Select this component when interfacing with high-resolution imagers requiring aggregated data streams. Ensure the downstream processor supports the required MIPI CSI-2 lane count and data rate. Verify cable length and type compatibility, as the device relies on adaptive equalization for signal integrity over coaxial or STP media. Check if the application requires Power-over-Coax capabilities or specific diagnostic features like line fault detection.

Part Context

The TDES954 is part of Texas Instruments' V3Link family of serializers and deserializers. It is specifically designed to pair with the TSER953 serializer to extend camera links over long distances. This chipset architecture simplifies the design of multi-camera systems by providing a robust solution for transmitting high-bandwidth video data while maintaining low latency and precise synchronization between multiple sensor inputs.
