TDA9981A Datasheet | NXP Semiconductors

description The TDA9981A is an HDMI transmitter (which also supports DVI) that enables a 3 × 8-bit RGB or YCBCR 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 k Hz) and the additional information required by all the HDMI 1.2a standards. In order to be patible with most applications, the TDA9981A integrates a full programmable input formatter and color space conversion block. The video input formats accepted are YCBCR 4 : 4 : 4 (up to 3 × 8-bit), YCBCR 4 : 2 : 2 semi-planar (up to 2 × 12-bit), YCBCR 4 : 2 : 2 pliant with ITU656 and ITU656-like (up to 1 × 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-pliant 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. 2.
