功能特点
技术参数
• 4 HDMI inputs. or 3 HDMI inputs and 3 MHL inputs. 1 output HDM[/DVI link.
• HDMI 1.4 RX, TX & MHL 1.2 receive compliant.
• Supports HDCP version 1.4 specification.
• Supports SPDIF audio outputs or 7.1 channels 12S outputs.
• Supports one channel ARC function on HDMI link, or ARC TX only or ARC RX only.
• 4 TMDS channels per link, supporting data rate up to 3.4 Gbps.
• Supports deep color up to 16-bit.
• Built-in pre-emphasizer which allows data transmission on long cables.
• Advanced on-die-termination calibration with automatic control.
• Automatic output disable feature for reduced power dissipation.
• Adaptive EQ can self-adapt variety of cables.
• SV tolerance DDC 10, minimize bom cost.
• Support fast switching funciton.
• 100-lead, 12mmx12mm LQFP, RoHS-compliant package.
The LT8641SXE is a four-to-one (4:1) switch ideally suited for use in the back panel of HDTV and A/V receivers, allowing consumers to connect multiple HDMI-enabled devices such as high-definition DVD players, set top boxes and game consoles. The LT8641SXE switch selects a single HDMI or Digital Visual Interface (DVI) signal from the four receiver ports and generates HDMI/DVI audio/video output, as well as DDC/HPD switching, in full compliance with the HDMI and DVI specifications. The LT8641SXE also acts as a HDMI receiver. It extracts the digital audio information from the HDMI packet, and recovers digital audio to I2S/SPDIF interface. So it can be applied to the multi-channel audio amplifier for best audio effect. This feature can enable an external HDMI switching box acts as a home entertainment box that can output up to 8-channel high quality audio signal for the best audio effect.

Description
The LT8641SXE is a Transition Minimized Differential Signaling (TMDS) switch that enables the connection of multiple High-Definition Multimedia Interface (HDMI) source devices to high-definition television (HDTV). Based on the HDMI 1.4 specification, LT8641SXE is an advanced TMDS switch that delivers a cost-effective method for manufacturers to add additional HDMI ports to their HDTV. Multiple HDMI ports allow consumers to connect variety HDMI-enabled sources to their HDTV. It supports HDCP 1.4 specifications, and Audio Return Channel function.The LT8641SXE is a four-to-one (4:1) switch ideally suited for use in the back panel of HDTV and A/V receivers, allowing consumers to connect multiple HDMI-enabled devices such as high-definition DVD players, set top boxes and game consoles.
