TMDS442 4-to-2 HDMI Switch
The TMDS442, 4-to-2 port DVI/HDMI switch, allows up to 4 digital video interface (DVI) or high-definition multimedia interface (HDMI) ports to be switched to two independent display blocks. The essential requirement of picture-in-picture display from two digital audiovisual sources is having two individual DVI or HDMI receivers in a digital display system. TMDS442 supports two DVI or HDMI receivers to enable multiple-source selection (picture-in-picture), as well as supports acting as a 4-input 1-output video switch.
Each input or output port contains one 5-V power indicator (5V_PWR), one hot plug detector (HPD), a pair of I2C interface signals (SCL/SDA), and four TMDS channels supporting data rates up to 2.25 Gbps
