1. General description
2. Features
The TDA9981A is an HDMI transmitter (which also supports DVI) that enables a 3
RGB or YC
version), up to 4 I
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 YC
2
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 I
