1. General Description

The LT8522EX is Lontium’s matrix switch chip that supports both two inputs (VGA and HD-DVI) and two outputs (VGA and HD-DVI) based on ClearEdge Technology.
The HD-DVI input interface is compliant with the HD-DVI 1.4 (High Definition Multimedia Interface) specification. It can also support Dual-Mode DP with HD-DVI interface. For backward compatibility, this matrix switch also includes two high performance analog interfaces (VGA input and VGA output). It has two high quality digital audio interfaces (audio input and audio output) that support 8-channel audio.
The LT8522EX is offered in a 100-pin TQFP package, with operating temperature range of -40℃ to +85℃.
