3比1的DVI / HDMI切换 3-TO-1 DVI/HDMI SWITCH
The TMDS341 is a 3-port digital video interface DVI or high-definition multimedia interface HDMI switch that allows up to 3 DVI or HDMI ports to be switched to a single display terminal. Four TMDS channels, one hot plug detector, and an I2C interface are supported on each port. Each TMDS channel allows signaling rates up to 1.65 Gbps.
The active source is selected by configuring source selectors, S1, S2, and S3. The selected TMDS inputs from each port are switched through a 3-to-1 multiplexer. The I2C interface of the selected input port is linked to the I2C interface of the output port, and the hot plug detector HPD of the selected input port is output to HPD_SINK. For the unused ports, the I2C interfaces are isolated, and the HPD pins are kept low.
Termination resistors 50-, pulled up to VCC, are integrated at each receiver input pin. External terminations are not required. A precision resistor is connected externally from the VSADJ pin to ground for setting the differential output voltage to be compliant with the TMDS standard. When the output is connected to a standard TMDS termination and OE is high, the output is high impedance.
The TMDS341 provides fixed 8-dB input equalization and selectable 3-dB output de-emphasis to optimize system performance through 5-meter or longer DVI compliant cables. The device is characterized for operation from 0°C to 70°C.
