  • Type A plug: the most common HDMI plug, 13.9 mm wide, 19 pins, designed with one set digital video TMDS lines (Single-Link)
  • Cable
    • Category 1 Standard cable without HEAC: the cable meets test spec with a max clock frequency of 74.25 MHz (or roughly 2 Gbps, or 720p and 1080i)
    • Category 2 High Speed cable without HEAC: the cable meets test spec with a max clock frequency of 340 MHz (or roughly 8 Gbps, or 4k x 2k and 3D)
    • Category 1 Standard cable with HEAC: the cable meets test spec with a max clock frequency of 74.25 MHz (or roughly 2 Gbps, or 720p and 1080i)
    • Category 2 High Speed cable with HEAC: the cable meets test spec with a max clock frequency of 340 MHz (or roughly 8 Gbps, or 4k x 2k and 3D)
    • Category 1 Standard automotive cable: the cable used in cars and trucks which meets the test spec with a max clock frequency of 74.25 MHz (or 2 Gbps, or 720p and 1080i)
  • Transmitter
  • Receiver sensitivity
    • the capability to sense the receiver connectivity and working behavior
    • detects the presence of the 50 W pull-up resistor RT on the TMDS clock channel of the downstream side
    • This feature is very useful when the receiver recovers from an off-state and does not generate a HPD transition HIGH-to-LOW-to-HIGH. In this particular case, RxSense will generate an interrupt so that the chip restarts sending video
