USB‑C Lane Configuration
The host controller of the USB-C input can be configured to operate in one of two modes:
• 2 Lanes, up to 4K/30 video — Two high speed data lanes operate in HBR2 mode
(5.4 Gbps x 2 lanes = 10.8 GBps).
NOTE: The 2 Lanes mode helps ensure compatibility with hybrid USB-C extension cables that have two
optical channels for video and two copper channels for data.
•
4 Lanes, up to 4K/60 video (default) — All four high speed lanes operate in HBR2 mode
(5.4 Gbps x 4 lanes = 21.6 Gbps).
This can be changed via SIS commands (see
Video Mute
There are three options for video mute:
•
Output Mute Off (default) — The video input and audio signal is passed to the output.
• Output Mute On — The video output is muted (black), but sync and 5 V is still present. If present, the
embedded audio is still passed to the sink device.
•
Output Sync Mute On — The video output, sync, and 5 V are disabled. The embedded audio is not passed
to the sink device. This allows the display to sleep if there is no signal present on the selected input.
This can be changed via SIS command (see
NOTE: Video mute reverts to default (unmuted) after a power cycle.
Auto Input Configuration
If video signal is present on the selected input, the digital or analog input audio embedded within the video signal
is transmitted over the TMDS channel to the receiver. Select the audio on the input of the transmitter via SIS
Input Audio Format
command (see
The audio input selections are:
• Auto — The transmitter selects between digital and analog audio based on the digital audio input signal.
•
Digital audio is selected by default.
• Analog audio is selected when digital audio is not detected.
•
Forced Digital — Digital audio is passed over the DTP output.
• Forced Analog — Analog audio is passed over the DTP output.
Output Audio Mute
The analog audio or digital embedded audio on the DTP/HDBT output can be muted via SIS command (see
Audio Mute
on page 29).
NOTE: Audio mute reverts to default (unmuted) after a power cycle.
