The Lattice Semiconductor SiI9535 Port Processor is the latest HDMI® port processor targeted at Audio Video Receiver (AVR), Home Theater in a Box (HTiB), and Soundbar applications. The port processor features InstaPort™ S and InstaPrevue™ technologies, Mobile High-definition Link 2.1 (MHL®), 300 MHz HDMI, On-screen Display (OSD), and Audio Return Channel (ARC).

MHL allows the user to attach a device to the HTiB or soundbar and view high-definition content while the mobile device battery is charging. MHL 2.1 supports 3D and PackedPixel Mode (PPM) in SiI9535 port processor and is supported on two input ports.

The SiI9535 port processor offers an extensive set of audio features, including audio extraction and insertion. Multi-channel audio from the active HDMI input can be extracted and sent to the audio output port. Additionally, a 2-channel PCM or bitstream audio from an audio DSP or an SoC can be inserted and sent to the HDMI output.

The SiI9535 port processor supports an ARC transceiver that is configurable as either receiver or transmitter. As an ARC receiver in an AVR or HTiB design, the HDMI transceiver output can receive an ARC signal from a Digital Television (DTV). The ARC channel is configurable as an ARC transmitter, and data from S/PDIF can be routed to the ARC transmitter.
