The TDA9981A is an HDMI transmitter (which also supports DVI) that enables a 3 x 8-bit RGB or YCB CR video stream (with a pixel rate up to 150 MHz for the TDA9981AHL/15 version), up to 4 I²S-bus audio streams (with an audio sampling rate up to 192 kHz) and the additional information required by all the HDMI 1.2a standards.
In order to be compatible with most applications, the TDA9981A integrates a full programmable input formatter and color space conversion block. The video input formats accepted are YCB CR4 : 4 : 4 (up to 3 x 8-bit), YCB CR4 : 2 : 2 semi-planar (up to 2 x 12-bit), YCB CR4 : 2 : 2 compliant with ITU656 and ITU656-like (up to 1 x 12-bit).
For ITU656-like formats, double edges are supported so that data can be sampled on rising and falling edges.
The TDA9981A also includes a HDCP 1.1-compliant cipher block. The HDCP key set is stored internally in a One Time Programmable (OTP) non-volatile memory for maximum security.
The device can be controlled via an I²C-bus interface
