The Lattice Semiconductor (formerly Silicon Image) SiI9573 and SiI9575 Port Processor is the latest generation HDMI® port processor targeted at audio video receivers, Home Theater in a Box (HTiB), and Digital TVs (DTVs). The port processor has many innovative features such as InstaPort® technology, InstaPrevue technology, Mobile High-definition Link (MHL®), ViaPort Matrix Switch (the SiI9575 device only), and Audio Return Channel (ARC).
The SiI9575 port processor offers an extensive set of audio features including audio extraction and insertion. Audio from the active HDMI input is sent to the main or subaudio output port. High-Bitrate (HBR) audio is supported on the main audio output port. Additionally, a 2-channel I2S or an S/PDIF input receives PCM or bit stream audio from an audio DSP or a DTV SoC, and output to either the main or sub-HDMI output, or both.
The SiI9575 device supports ViaPort Matrix Switch. While the main HDMI output selects one of the HDMI inputs, the second HDMI output can select another HDMI input or parallel video input. This is ideal for AVR Zone 2 support or PIP/POP function in DTV.
