·Single Physical Layer PHY with support for HDMI 1.4 and 2.0 operation
·For HDMI operation, support for the following:
HPD input analog comparator
13.5–600MHz input reference clock
Up to 10-bit Deep Color modes
Up to 18Gbps aggregate bandwidth
Up to 1080p at 120Hz and 4kx2k at 60Hz HDTV display resolutions and up to QXGA graphic display resolutions
3-D video formats
·Link controller flexible interface with 30-, 60- or 120-bit SDR data access
·Support HDCP 1.4/2.2
❶ SDA，SCL在连接器端是5V电平；CEC信号在连接器端是3.3V电平。需要做电平转换。
二极管的作用是防止电流从设备端倒灌进入主板，建议选用压降小的肖特基二极管。
❷ 关于5V电压也有一些注意事项，其电流不会超过55mA，在走线时注意走线宽度即可。All HDMI Sources shall be able to supply a minimum of 55 mA to the +5V Power pin.A Sink shall not draw more than 50 mA of current from the +5V Power pin. When the Sink is powered on, it can draw no more than 10mA of current from the +5V Power signal.
❸ ESD器件请靠近HDMI接口放置，推荐使用HDMI2.0专用的ESD器件，电容最大不超过0.4pF。
❹ 关于热插拔检测引脚HPD在协议规范中也有其特定的工作范围，但是在OK3399-C平台上只需串联1k限流电阻即可。
