Description
The LT8621SXE-M is a fully integrated HDMI 1.4 switch
that enables the connection of two High-Definition
Multimedia Interface (HDMI) source devICes to a remote
high-definition television (HDTV). The SPDIF digital audio
output allows customers connect an audio amplifier for
better audio quality and control. Based on the HDMI
version 1.4, equipped with adaptive equalization of wide
range, LT8621SXE-M is an advanced TMDS switch that
delivers a cost-effective method for HDMI signal repeating,
switching and audio extraction. . With support of HDCP
version 1.4 specifications, if used in pairs, it can provide a
very cost effective HDMI signal extension solution with
CAT6 cable with bandwidth up to 3Gb/s.
The LT8621SXE-M is integrated with a MCU for chip
programming and EDID processing. The two HDMI ports
can be designed as two HDMI connector ports or
designed as RJ45 connector ports for CAT6 cable HDMI
extension. The LT8621SXE-M also acts as a HDMI
receiver. It extracts the digital audio information from the
HDMI packet, and recovers digital audio to IIS/SPDIF
interface. This feature can enable an external HDMI
switching box acts as a home entertainment box that can
output up to 2-channel high quality audio signal for the
best audio effect
