TDA9984A
Datasheet
General description
The TDA9984A is a HDMI transmitter (which also supports DVI) which allows mixing a 3 x 8-bit RGB or Y-CB-CR video stream with a pixel rate up to 150 MHz together with up to 4 S/PDIF or I2S-bus audio streams with an audio sampling rate up to 192 kHz.
A programmable upscaling block allows creating a 1080p output from a standard definition input. An intrafield deinterlacer is included in the scaler.
In order to be compatible with most applications, and thanks to the integration of a fully programmable input formatter and color space conversion block, the video input formats accepted also include Y-CB-CR 4 : 4 : 4 (up to 3 x 8-bit), Y-CB-CR 4 : 2 : 2 semi-planar (up to 2 x 12-bit) and Y-CB-CR 4 : 2 : 2 compliant with ITU656 (up to 1 x 12-bit). In case of ITU656-like format, the input pixel clock can be made active on both edges.
The TDA9984A includes a HDCP 1.2 compliant cipher block. The HDCP key set can be stored internally in a non-volatile OTP memory for maximum security.
The TDA9984A includes a true I2C-bus master interface for DDC communication for EDID purpose and HDCP purpose.
The TDA9984A can be controlled by an I2C-bus interface.
Features
- 3 x 8-bit video data input buses; CMOS and LV-TTL compatible
- Horizontal synchronization, vertical synchronization and data enable inputs or VREF, HREF and FREF inputs which can be used for synchronization
- Pixel rate clock input can be made active on one or both edges; selectable via I2C-bus
- 4 I2S-bus audio input channels, 1 S/PDIF channel; audio data rate up to 192 kHz per input for both standards
- 250 MHz to 1.50 GHz TMDS transmitter operation
- Programmable input formatter and upsampler/interpolator allows input of any of the 4 : 4 : 4 or 4 : 2 : 2 semi-planar and 4 : 2 : 2 ITU656-like formats
- Programmable color space converter allows to input RGB video data and to output RGB or Y-CB-CR 4 : 2 : 2 HDMI video data, or to input Y-CB-CR video data and to output RGB or Y-CB-CR 4 : 2 : 2 HDMI video data; converter can be passed
- Upscaler allows creating a 1080p output from a standard definition input by using intelligent edge interpolation
- Repetition of video samples as required by the HDMI standard
- Insertion of HDMI additional information such as InfoFrames
- Downstream availability using hot plug detection (HPD input) and receiver detection (RxSense circuit)
