Overview
The DS90UB947TRGCRQ1 is a high-performance OpenLDI to FPD-Link III serializer produced by Texas Instruments. This device is designed to serialize OpenLDI input signals into high-speed serial streams, supporting video resolutions up to WUXGA (1920x1200) and 1080p60 with 24-bit color depth. It is particularly suited for automotive and industrial applications where high-speed data transmission over long distances is required.
The device is part of the FPD-Link III family, which offers robust and reliable data transmission over cost-effective coaxial or shielded twisted-pair cables. It integrates video, audio, and control data into a single or dual differential link, reducing the interconnect size and weight while simplifying system design.
