STMicroelectronics HDMI2C1-6C1 technical specifications, attributes, parameters and parts with similar specifications to STMicroelectronics HDMI2C1-6C1.

• For HDMI 1.4, 2.0 & 2.1 application, operating temperature from -40 to 85 °C

• 8 kV contact ESD protection on connector side (IEC 61000-4-2 level 4)

• Supports direct connection to low-voltage HDMI ASIC and/or CEC driver (down to 1.8 V)

• High integration level in 1 package

• DDC (I2C) link protection, bi-directional signal conditioning circuit and dynamic pull-up

• CEC bus protection, bi-directional level-shifter, back drive protection, and independent structure from the main power supply

• HEAC link protection and line matching

• HPD pull down, signal conditioning with level shifter and back drive protection

• Short-circuit protection on 5V output

• Proposed in 500 µm pitch QFN 18L 3.5 x 3.5

• Benefits:

– Minimal PCB footprint in tablet, set-top box, game console and other consumer application

– Protection of ultra-sensitive HDMI ASICs

– Wake-up from stand-by through CEC bus

– Ultra-low power consumption in standby mode

– Improved HDMI interface ruggedness and user experience

– Long and/or poor quality cable support with a dynamic pull-up on DDC bus

• Complies with the following standards:

– Dedicated for HDMI 1.4, 2.0 and 2.1 version

– IEC 61000-4-2 level 4

– JESD22-A114D level 2

Consumer and computer electronics HDMI Source device such as:

• Tablet, smartphone and notebook

• HD set-top boxes

• Game console

• DVD and Blu-Ray Disk systems

• PC graphic cards

The component offers two buffers, integrating signal conditioning dynamic pull-up on the DDC bus for maximum system robustness and signal integrity. A bidirectional CEC block is integrated, able to wake up the application from standby mode (all power supply off, except the CEC power supply). The +5 V supplied to the cable is protected against accidental surge current and short circuit. All these features are provided in an 18 leads QFN package featuring natural PCB routing, cost optimization and saving space on the board.

The HDMI2C1-6C1 is a simple solution that provides HDMI designers with an easy and fast way to reach full compliance with the stringent HDMI CTS on a wide temperature range. STMicroelectronics proposes also a large range of high-speed ESD protections and common mode filter (ECMF series) dedicated to the TMDS lanes giving the flexibility to the designer to filter and protect these (high-speed video link against ESD strikes and EMC issues).
