描述 Description

Pericom Semiconductor’s PI3HDMI412AD, active-drive switch solution is targeted for high-resolution video networks that are based on DVI/HDMITM standards, and TMDS signal processing. The PI3HDMI412AD is an active single TMDS channel to two TMDS channel DeMux with Hi-Z outputs. The device drives differential signals to multiple video display units. It provides three controllable output swing levels that can be controlled through pin control or I2C control, depending on the mode select pin. The swing levels are 500mV, 700mV & 1000mV. This solution also provides a unique advanced pre-emphasis technique to increase rise and fall times which are reduced during transmission across long distances.
