TDES954RGZR

Overview

The TDES954RGZR is a dual V3Link deserializer hub manufactured by Texas Instruments, designed for high-speed, high-resolution camera and sensor applications. It aggregates serialized data from one or two independent sources over V3Link interfaces and outputs MIPI CSI-2 compliant signals. The device supports up to four data lanes with scalable rates of 400 Mbps, 800 Mbps, 1.5 Gbps, or 1.6 Gbps per lane. It operates within an ambient temperature range of –20°C to +85°C and accepts input via single-ended coaxial or shielded twisted-pair cables. Key electrical parameters include a recommended VDD18 supply voltage of 1.71 V to 1.89 V and a reference clock frequency of 23 MHz to 26 MHz.

Feature Summary

• Dual deserializer hub architecture aggregating one or two active sensors
• MIPI DPHY version 1.2 / CSI-2 version 1.3 compliance
• Adaptive receive equalization for cable loss compensation
• Power-over-coax (PoC) compatible transceiver design

Applications

• Video Surveillance systems
• Industrial Robots
• Machine Vision equipment
• Patient Monitoring and Diagnostics devices
• Appliances with imaging capabilities

Procurement Notes

Verify the specific ordering suffix 'RGZR' against the manufacturer's current orderable addendum to confirm package dimensions and tape-and-reel specifications. Ensure that the I2C pull-up resistor values align with the selected VDDIO voltage level, as the datasheet recommends external resistors for proper bus operation. Confirm that the PCB layout adheres to the thermal and decoupling guidelines provided in the application section to maintain signal integrity.

Selection Notes

Select this component when designing systems requiring aggregation of multiple sensor streams into a single MIPI CSI-2 interface. It is suitable for applications utilizing TSER953 serializers or DVP mode serializers. Consider the device's support for replicate mode if parallel processing or data logging of duplicated video streams is required. Verify that the downstream processor supports the specific MIPI CSI-2 lane configuration and data rate needed for the target resolution and frame rate.

Part Context

The TDES954 belongs to the V3Link family of serializers and deserializers from Texas Instruments. It is typically paired with the TSER953 serializer to form a complete transmission solution for high-bandwidth sensor data. This chipset approach allows for long-distance transmission over simple cabling while maintaining low latency and high reliability for automotive and industrial vision applications.
