DS90UB981-Q1

The DS90UB981-Q1 is a high-speed serializer from Texas Instruments designed for automotive and industrial applications requiring reliable data transmission over long distances. It supports up to 3 Gbps per lane, enabling efficient conversion of parallel LVDS (Low-Voltage Differential Signaling) data into serialized serial data streams. This device operates with a wide supply voltage range of 3.3 V ±5%, making it suitable for systems with varying power conditions. The chip features integrated clock recovery and deserializer functionality, reducing the need for external components and simplifying system design. One of its key characteristics is compliance with AEC-Q100 Grade 1 qualification, ensuring robust performance in harsh automotive environments such as extreme temperatures (-40°C to +125°C), vibration, and electromagnetic interference. It includes built-in diagnostics and error detection mechanisms like CRC checking and link monitoring, which enhance system reliability and fault tolerance. Additionally, the DS90UB981-Q1 supports both single-ended and differential input modes, providing flexibility in interfacing with various sensor and camera modules. This serializer is commonly used in advanced driver-assistance systems (ADAS), including surround-view cameras, forward-facing cameras, and night vision systems. Its ability to transmit high-resolution video signals from image sensors to processing units over twisted-pair cables or coaxial cables makes it ideal for compact, lightweight, and cost-effective camera solutions. The device also supports multiple video formats such as MIPI CSI-2 and raw Bayer data, allowing seamless integration with modern imaging pipelines. Power efficiency is another notable feature, with low quiescent current and sleep mode support that minimizes energy consumption during idle periods. The DS90UB981-Q1 integrates an internal PLL (Phase-Locked Loop) for precise clock generation and jitter attenuation, ensuring stable signal integrity even over extended cable runs. It is available in a small 48-pin QFN package, optimizing board space usage while maintaining thermal performance. Designed for use with Texas Instruments’ complementary deserializer ICs such as the DS90UB982-Q1, the DS90UB981-Q1 enables full-duplex communication in automotive camera systems. Its compatibility with industry-standard protocols and robust packaging make it a preferred choice for OEMs developing safety-critical vision systems. Overall, this device delivers high bandwidth, low latency, and enhanced reliability—key requirements for next-generation automotive and industrial imaging applications.
