TDA19988AHN Low power, 150 MHz pixel rate HDMI 1.4a transmitter with 3 x 8-bit video inputs, HDCP and CEC support

TDA19988 is a very low power and very small size High-Definition Multimedia Interface (HDMI) 1.4a transmitter. It is backward compatible DVI 1.0 and can be connected to any DVI 1.0 or HDMI sink.

This device is primarily intended for mobile applications like Digital Video Camera (DVC), Digital Still Camera (DSC), Portable Multimedia Player (PMP), Mobile Phone and Ultra-Mobile Personal Computer (UM PC), new PC tablet and MID where size and power are key for battery autonomy.

This device is also targeting STB HDMI output applications. This part replaces previous TDA9981 Transmitters with increased features and better performances.

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

In order to be compatible with most applications, TDA19988 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) and YCbCr 4 : 2 : 2 compliant with ITU656 (up to 1 × 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).

TDA19988AHN and TDA19988AET only include a 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.

TDA19988 supports xvYCC HDMI 1.4a feature.

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

TDA19988 embeds I²C-bus master interface for DDC-bus communication to read EDID and to manage HDCP (TDA19988AHN and TDA19988AET only).

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