TDA9981B Datasheet | NXP Semiconductors

description The TDA9981B is an HDMI transmitter (which also supports DVI) that enables a 3 × 8-bit RGB or YCb Cr 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 k Hz) and the additional information required by all the HDMI 1.2a standards. In order to be patible with most applications, the TDA9981B integrates a full programmable input formatter and color space conversion block. The video input formats accepted are YCb Cr 4 : 4 : 4 (up to 3 × 8-bit), YCb Cr 4 : 2 : 2 semi-planar (up to 2 × 12-bit), YCb Cr 4 : 2 : 2 pliant 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 patible 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 k Hz I 250 MHz to 1.50 GHz HDMI transmitter operation I Programmable input formatter and upsampler/interpolator allows input of any of the 4 : 4 : 4, 4 : 2 : 2 semi-planar, 4 : 2 : 2 ITU656 and ITU656-like formats I Programmable color space converter: N RGB to YCb Cr N YCb Cr to RGB I Controllable via I2C-bus I Low power dissipation I 1.8 V and 3.3 V power supplies I Power-down mode I Hard reset ..
