TMDS442PNP

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. The 5-V power

indicator and the hot plug detector are pulled down with internal resistors, forcing a low state on these pins until

receiving a valid high signal. The I2C interface is constructed by an I2C repeater circuit to isolate the capacitance

form both ends of the buses. TMDS receivers integrate 50-Ω termination resistors pulled up to VCC, which

eliminates the need for external terminations. An 8-dB input equalization cooperates to each TMDS receiver

inputs to optimize system performance through 5-meter or longer DVI or HDMI compliant cables.
