ATT2089 is a high-performance display bridge chip designed to convert LVDS (Low Voltage Differential Signaling) signals into MIPI DSI (Mobile Industry Processor Interface – Display Serial Interface) signals. It is ideal for applications where a legacy LVDS interface needs to drive modern MIPI display panels, such as:
Industrial control displays
Medical equipment terminals
Smart home control panels
Automotive dashboards and infotainment screens
Portable embedded devices
ATT2089 offers excellent compatibility, stability, and low power consumption, making it a reliable solution for LVDS to MIPI conversion.

[Main Controller with LVDS Output] ---> [ATT2089 LVDS Input] ==> [ATT2089 MIPI Output] ---> [MIPI DSI Display Panel]
ATT2089 bridges LVDS signals from a legacy controller to modern MIPI-compatible display modules.
Signal Matching and Layout
LVDS input should follow differential impedance control (100Ω differential impedance).
MIPI signals require matched trace length and controlled impedance to prevent reflection and crosstalk.
Power Isolation and Filtering
Separate power supplies for 1.2V core and 3.3V I/O are required.
Recommended to add decoupling capacitors near power pins.
Initialization and Configuration
ATT2089 can be configured via I²C or SPI interface.
Parameters such as clock frequency, output lane number, and timing format are set during initialization.
Compatibility Check
Ensure the display panel supports MIPI DSI and is compatible with the selected output configuration (lane count, clock speed, etc.).
Reference design documents are provided for fast integration.
Legacy System Upgrade
Upgrade existing LVDS-based designs to MIPI displays without replacing the main controller.
Automotive Displays
Bridge automotive LVDS output to high-resolution MIPI displays for dashboards or infotainment systems.
Smart Home Terminals
Cost-effective LVDS-based SoCs can drive modern MIPI screens via ATT2089.
The ATT2089 package includes a full set of development resources:
Datasheet
Application Notes
Reference PCB Design
Register Configuration Tables
Example Driver Code (C Language)
Linux or RTOS systems on the host controller can easily integrate with the ATT2089.
ATT2089 is a cost-effective and integration-friendly LVDS to MIPI bridge solution suitable for various embedded display applications. It solves compatibility challenges in mixed-interface environments and enables smooth system upgrades.
