HDMI transmitter — what this part does
The NXP TDA9981BHL/15/C1557 is an HDMI transmitter, the device that serialises video and audio data into an HDMI stream for display interfaces. It takes parallel video input from a graphics controller or SoC and outputs a single-link HDMI signal, handling the protocol framing, TMDS encoding, and auxiliary channel management internally. This part is used in set-top boxes, media players, digital signage controllers, and any embedded system that needs to drive an HDMI display from a baseband video source.
No last-time-buy or end-of-life notice applies. Bulk packaging means the parts ship in tubes or trays rather than tape-and-reel, which matters for pick-and-place setup if your line expects reel-fed components.
