Overview
The Texas Instruments SN65DSI86ZQER is a sophisticated DSI to eDP (embedded DisplayPort) bridge designed to facilitate high-speed video data transmission. This device is part of the SN65DSI86/SN65DSI86-Q1 family and is engineered to support dual-channel MIPI D-PHY receiver configurations with four lanes per channel, operating at speeds up to 1.5Gbps per lane and a maximum input bandwidth of 12Gbps. It is particularly suited for applications requiring high-resolution video output, such as WQXGA (2560 × 1600) at 60 frames per second and true HD (1920 × 1080) at up to 120fps with 24bpp color depth. The device is also AEC-Q100 qualified, making it suitable for automotive applications.
