Inputs
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-
), 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.
