General description

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).
