DESCRIPTION

The TMDS351 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 a digital display control (DDC) interface are supported on each port. Each TMDS channel supports

signaling rates up to 2.5 Gbps to allow 1080p resolution in 12-bit color depth.

When S1 is high and S2 is low, all input terminations are disconnected, TMDS inputs are high impedance with

standard TMDS terminations, all internal MOSFETs are turned off to disable the DDC links, and all HPD outputs

are connected to the HPD_SINK. This allows the initiation of the HDMI physical address discovery process.

Termination resistors (50-Ω), pulled up to VCC, are integrated at each TMDS receiver input. 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.

The TMDS351 provides two levels of receiver input equalization for different ranges of cable lengths. Each

TMDS receiver owns frequency responsive equalization circuits. When EQ sets low, the receiver supports the

input connection in short range HDMI cables. When EQ sets high, the receiver supports the input connection in

long range HDMI cables. The TMDS351 supports power saving operation. When a system is under standby

mode and there is no digital audio/visual content from a connected source, the 3.3-V supply voltage, VCC, can be

powered off to minimize power consumption from the TMDS inputs, outputs, and internal switching circuits. The

HPD, DDC, and source selection circuits are powered up by the 5-V supply voltage, VDD, to maintain the system

hot plug detect response, the DDC link from the selected source to the sink under system standby operation. The

device is characterized for operation from 0°C to 70°C.
