DS90UB638TRGZTQ1

Overview

The DS90UB638TRGZTQ1 is a single-input deserializer from the Texas Instruments DS90UB638-Q1 series, designed for FPD-Link III interfaces. It supports data rates up to 4.16 Gbps and outputs MIPI CSI-2 compliant signals with scalable lane speeds of 400 Mbps, 800 Mbps, 1.5 Gbps, or 1.6 Gbps per lane. The device accommodates 1 to 4 data lanes and up to four virtual channels within a 48-pin VQFN package (7.00 mm × 7.00 mm). Operating conditions range from -40°C to +105°C, powered by 1.8V (±5%) and optionally 1.1V supplies.

Feature Summary

• Adaptive receive equalization automatically compensates for cable loss characteristics without additional programming.
• Supports Power-over-Coax applications with integrated low-latency bidirectional control channel for I2C and GPIO communication.
• Includes advanced diagnostics such as CRC protection, sensor data integrity checks, and line fault detection.

Applications

• Advanced driver assistance systems (ADAS)
• Automotive satellite RADAR and LIDAR modules
• Camera monitor systems (CMS)

Procurement Notes

Verify that the component matches the specific automotive grade requirements and AEC-Q100 qualification standards. Confirm the package type and pin configuration align with the target PCB layout. Ensure power supply sequencing meets the recommended operating conditions before activation.

Selection Notes

Select this model when a single-channel FPD-Link III input is required for high-speed video transmission. Consider the internal LDO option if an external 1.1V supply is not available. Verify compatibility with the paired serializer, such as the DS90UB635-Q1, for optimal system performance.

Part Context

This component belongs to the DS90UB638-Q1 family of deserializers manufactured by Texas Instruments. It is specifically engineered for automotive environments requiring robust signal integrity and diagnostic capabilities over coaxial or shielded twisted-pair cables.
