TDA9981B

www.DataSheet4U.com TDA9981B HDMI transmitter up to 150 MHz pixel rate with 3 × 8-bit video inputs and 4 × I2S-bus with S/PDIF Rev. 01 — 4 July 2008 Product data sheet 1. General description The TDA9981B is an HDMI transmitter (which also supports DVI) that enables a 3 × 8-bit RGB or YCbCr video stream (with a pixel rate up to 150 MHz for the TDA9981BHL/15 version), up to 4 I2S-bus audio streams (with an audio sampling rate up to 192 kHz) and the additional information required by all the HDMI 1.2a standards. In order to be compatible with most applications, the TDA9981B 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), YCbCr 4 : 2 : 2 compliant with ITU656 and ITU656-like (up to 1 × 12-bit). For ITU656-like formats, double edges are supported so that data can be sampled on rising and falling edges. The device can be controlled via an I2C-bus interface. 2. Features I 3 × 8-bit video data input bus, CMOS and LV-TTL compatible I Horizontal synchronization, vertical synchronization and Data Enable (DE) inputs or VREF, HREF and FREF could be used for input data synchronization I Pixel rate clock input can be made active on one or both edges (selectable by I2C-bus) I The TDA9981B has 4 I2S-bus audio input channels and 1 S/PDIF channel; audio sampling rate up to 192 kHz I 250 MHz to 1.50 GHz HDMI transmitter operation I Programmab...
