Product Overview
The LT7911UXC_U3B00AED is Lontium’s high-performance interface converter for multimedia, smart display and VR/AR equipment. It bridges USB Type-C/DP 1.4a/eDP inputs to 1/2/4-channel MIPI DSI/CSI/LVDS displays, with built-in video scaler supporting native 8K×4K@30Hz (YUV422), compressed 8K@60Hz and 4K×2K@120Hz.
Equipped with on-board SPI Flash, multi-channel HD audio output, USB PD 3.0 and adaptive link training for stable long-cable signal transmission. Housed in BGA-169 (9×9mm), this single-chip IC fits automotive infotainment, industrial HMI, medical monitors and portable display devices.
Core Advantages
Versatile Multi-Port Interface Bridge Architecture
Supports seamless high-bandwidth cross-conversion between input standards (USB Type-C, DP 1.4a, eDP) and configurable 1/2/4-port output matrices (MIPI DSI, MIPI CSI, LVDS), eliminating the necessity for discrete multi-chip converter cascades.
Exceptional Ultra-High-Resolution Processing
Equipped with advanced internal dynamic video scaling engines and chroma sub-sampling routines capable of rendering crisp 8K video frames at 30Hz / 4K at 120Hz with minimal structural latency and HDR10/HDR12 support.
Integrated USB Power Delivery 3.0 Controller
Features embedded dual CC logic and PD 3.0 controller block that handles Type-C power negotiation natively, simplifying power-management paths over standard Type-C connectivity cables.
Robust Signal Re-Clocking and Integrity
Incorporates active high-performance internal DP equalizer and Phase-Locked Loop (PLL) configuration that stabilizes high-frequency clock distributions and mitigates jitter over extended PCB trace and cable paths.
Built-In HDCP 1.3/2.3 Repeater Engine
Native HDCP encryption/decryption repeater core supports protected media content transmission, fully compliant with global digital content protection standards.
