Smart Display Controller
SC1701 Series

Enables highly optimized and cost effective solutions for a broad range of in-vehicle remote display uses. Reduces the overall BOM and allows the realization of competitive and cost optimized systems. Performs all graphics processing, including safety and integrity related functions by its signature unit. Utilizing two display controllers allows flexible architectures with more than one display in a single chain. The future-proof design supports through its video link up to 12 Gbps uncompressed or equivalent to 28 Gbps video data by utilizing VESA DSC compression method.
