HDMI 1.3 transmitter with HDCP — what the standards list tells you
The AD9889BBCPZ-80 is an HDMI/DVI transmitter from the Advantiv® series, designed to encode digital video and audio into HDMI 1.3 or DVI 1.0 streams with HDCP 1.2 content protection. It also accepts ITU656 and CEA-861B video formats, making it a fit for set-top boxes and digital recorders that need to drive a display port. The 1.71V–1.89V core supply is tighter than a typical 1.8V rail — confirm your regulator holds within that window, especially under load transient.
Package and layout — 64-LFCSP with exposed pad
Housed in a 64-LFCSP-VQ (9x9) package with an exposed thermal pad. The pad needs a solid via stitch to the ground plane to pull heat out of the die; without it, junction temperature climbs fast under continuous HDCP authentication.
