2 MP MIPI® CSI-2 FPD-Link III serializer for 2MP/60fps cameras & radar

The DS90UB953-Q1 is an automotive-grade high-speed serializer designed to convert parallel image sensor data into a high-speed serial stream for transmission over a single differential pair using FPD-Link III technology. It is intended for use in camera-based systems where compact cabling, high data integrity, and low latency are required. The device interfaces directly with image sensors through a MIPI CSI-2 input and transmits video, control, and GPIO data over a single coaxial or shielded twisted pair cable. Integrated clocking and control features allow synchronization with remote deserializers, enabling robust communication in electrically noisy environments typical of automotive and industrial applications.

Functional Description

The device receives image data from a connected sensor through a MIPI CSI-2 interface and serializes this data for transmission over a high-speed differential link. In addition to video data, bidirectional control communication is supported through an embedded control channel, allowing configuration and monitoring of remote devices using an I²C interface. The serializer incorporates programmable GPIO functionality that can be used for control signaling or sensor monitoring, with the ability to transport these signals across the link. Internal clock generation and phase-locked loop circuitry support multiple clocking modes, enabling flexible system design with either local or remote reference clocks. The device also includes pattern generation capabilities for system testing and validation.

Electrical Characteristics

The component operates from multiple power domains supporting core logic, I/O, and phase-locked loop functions. It is designed to provide stable high-speed signal transmission with controlled impedance outputs and low jitter characteristics. The differential serial output supports reliable long-distance communication over coaxial or twisted-pair media. Input interfaces are optimized for compatibility with standard MIPI CSI-2 signaling, ensuring seamless integration with modern image sensors. The control interface uses an open-drain I²C protocol for configuration and communication.

Mechanical Characteristics

The device is provided in a compact quad flat no-lead package suitable for high-density PCB designs. The package includes an exposed thermal pad that serves both as a heat dissipation path and a low-impedance electrical ground connection. The small footprint and low profile make it well suited for space-constrained applications such as camera modules and embedded vision systems.

Environmental Characteristics

The DS90UB953-Q1 is qualified for automotive applications and is designed to operate reliably over extended temperature ranges and under conditions of electrical noise, vibration, and mechanical stress. The device is compatible with standard surface-mount assembly processes, including lead-free reflow soldering. Materials and construction comply with relevant environmental and reliability standards for automotive-grade electronic components.

Materials and Construction

The package body is constructed from high-temperature thermally stable materials suitable for reflow soldering. Electrical contacts are formed from copper-based alloys with plated finishes to ensure long-term conductivity, corrosion resistance, and mechanical durability. The exposed pad is designed to interface directly with the PCB ground plane for improved thermal and electrical performance.
