HDMI Interface transmitter

TDA19988 is a very low power and very small size High-Definition Multimedia Interface (HDMI) v. 1.4 transmitter. It is backward compatible DVI 1.0 and can be connected to any DVI 1.0 and 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) where size and very low power are mandatory for battery autonomy. It allows mixing 3 × 8-bit RGB or YCbCr video stream with a pixel rate up to 150 MHz together with one S/PDIF or two I2S-bus audio streams with an audio sampling rate up to 192 kHz. TDA19988 includes a HDCP 1.3 compliant cipher block. The HDCP keys are stored internally in a non-volatile OTP memory for maximum security.
