HDMI2.1 Transmitter PHY & Controller

Innosilicon HDMI TX IP is designed for transmitting video and audio data from a video source device to a display device, which is compatible with HDMI2.1, HDMI2.0 and HDMI1.4 specifications.
Innosilicon HDMI TX IP consists of the digital controller and the physical layer. The digital controller receives video, audio, synchronous signals and control signals from SoC logic and outputs encoded data to physical layer.
The physical layer contains 4 data channels, PLL, and bias circuit. Each data channel consists of serializer and driver. The serializer converts the parallel input data to 1-bit high speed serial stream and the driver converts the digital serial data to low swing differential signals with typical DC-coupled connection. The data rate is up to 12Gbps per channel. In HDMI2.0 and HDMI1.4 modes, the first data channel serves as the clock channel and transmits clock signal up to 340MHz to receiver. PLL generates the clocks required by data channels and the digital logic. The bias circuit generates voltage and current reference.
Innosilicon HDMI TX IP offers reliable implementation for HDMI interface, which can be integrated in the SOC used in multimedia device.
