Description
The STDVE103A integrates a 4-channel 3.4 Gbps
TMDS equalizer and a 3:1 switch to select one of
the three HDMI ports. The high-speed data paths
and flow-through pinout minimize the internal
device jitter and simplify the board layout. The
equalizer overcomes the jitter effects from lossy
cables. The buffer/driver on the output can drive
the TMDS output signals over long distances.
Also, STDVE103A integrates the 50 W
termination resistor on all the input channels to
improve performance and reduce board space.
The device can be placed in a low-power mode by
disabling the output current drivers.
The differential signal from the HDMI/DVI ports
can be routed through the STDVE103A to
guarantee good signal quality at the HDMI
receiver.
Designed for very low skew, jitter and low I/O
capacitance, the switch preserves the signal
integrity to pass the stringent HDMI compliance
requirements.
