HDMI i portable applikationer

Texas Instruments introducerer industriens første integrerede HDMI companion chip til portable applikationer (in english)

Texas Instruments (TI) has introduced the industry’s first integrated HDMI interface companion chip to the core HDMI controller for portable applications. The TPD12S015 incorporates all of the components required for an HDMI interface, including eight low-capacitance electrostatic discharge (ESD) clamps, I2C level shifters, and a DC/DC converter, saving 75 percent the board space and significantly reducing overall system cost when compared to discrete implementations.

Designers can use the TPD12S015 with TI’s OMAPTM applications processors or similar processors in a wide range of portable applications including smartphones, camcorders, digital still cameras and portable game consoles.  

Key features and benefits of the TPD12S015:
-  Internal boost converter generates 5 V from a 2.3-V to 5.5-V battery voltage, which eliminates the need for an on-board 5-V supply to drive the HDMI 5-V output pin.

- Matched HDMI Class-C connector pin-mapping eliminates board design layout skew that typically occurs with discrete implementations.

- Auto-direction sensing level shifter with integrated pull-ups and edge-rate control circuits eliminate the need for an additional on board I2C cable driver circuit.

- The DDC and CEC control lines can drive longer HDMI cable, amount to at least 750pF load, exceeding the HDMI standard defined 700pF maximum load. 

The TPD12S015 is in volume production today with samples ready to ship. This device comes in an industry-leading, small-footprint WCSP package (1.6 mm x 2.8 mm) with 0.4-mm pitch.
