TDA9983A

General description

The TDA9983A is an HDMI transmitter (which also supports DVI) that enables a 3 x 8-bit RGB or YC_BC_R video stream (with a pixel rate up to 150 MHz for the TDA9983AHW/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.

A programmable upscaling block enables a 720p/1080i output from a standard definition input. An intrafield deinterlacer is included in the scaler.

In order to be compatible with most applications, the TDA9983A integrates a full programmable input formatter and color space conversion block. The video input formats accepted are YC_BC_R 4 : 4 : 4 (up to 3 x 8-bit), YC_BC_R 4 : 2 : 2 semi-planar (up to 2 x 12-bit), YC_BC_R 4 : 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 TDA9983A also includes a HDCP 1.1 compliant cipher block. The HDCP key set is stored internally in a One Time Programming (OTP) non-volatile memory for maximum security.

The device can be controlled via an I²C-bus interface.
