TDF19988 Automotive, low power, 165 MHz pixel rate HDMI 1.4b transmitter with 3 x 8-bit video inputs and HDCP support

TDF19988 is a very low power and easy routing High-Definition Multimedia Interface (HDMI) 1.4b transmitter. It is backward compatible DVI 1.0 and can be connected to any DVI 1.0 or HDMI sink.

This device is intended for multimedia automotive applications from audio amplifier to A/V output of vehicle head unit, through Blu-ray player.

It allows mixing 3 x 8-bit RGB or YCbCr video stream at pixel rate up to 165 MHz together with one S/PDIF or four I²S-bus audio streams at audio sampling rate up to 192 kHz.

In order to be compatible with most applications, TDF19988 integrates a full programmable input formatter and color space conversion block. The video input formats accepted are YCbCr 4 : 4 : 4 (up to 3 x 8-bit), YCbCr 4 : 2 : 2 semi-planar (up to 2 x 12-bit) and YCbCr 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 one (SDR mode) or both edges (DDR mode).

TDF19988 includes optionally HDCP 1.4 compliant cipher block. The HDCP keys are stored internally in a non-volatile OTP memory for maximum security.

This device provides additional embedded features like CEC (Consumer Electronic Control). CEC is a single bidirectional bus that transmits CEC commands (like Standby from remote control) over the home appliance network connected through this bus. This eliminates the need of any additional device to handle this feature thus improving BOM (Bill Of Materials) of the whole system and enabling the connected devices (CEC enabled) to be controlled by only one remote control.

TDF19988 supports xvYCC HDMI 1.4b feature.

It can be switched to very low power Standby or Sleep modes to save power when HDMI is not used.

TDF19988 embeds I²C-bus master interface for DDC-bus communication to read EDID and to manage HDCP.

This device can be controlled or configured via I²C-bus interface
