Integrated HDMI Companion Chip Seeks Portable Apps

Introduced as the industry’s first integrated HDMI companion chip to the core HDMI controller for portable applications, the TPD12S015 incorporates all the major components required for an HDMI interface. These include eight low-capacitance ESD clamps, I2C level shifters, and a dc/dc converter. The device supports HDMI 1.3 data rates and provides IEC61000-4-2 (Level 4) ESD protection. An internal boost converter generates 5V from a 2.3V to 5.5V battery voltage, which eliminates the need for an on-board 5V supply to drive the HDMI 5-V output pin. Other features include matched HDMI Class-C pin-mapping and auto-direction sensing level shifter with integrated pull-ups and edge-rate control circuits. TEXAS INSTRUMENTS INC., Dallas, TX.
