General description
The STDVE103A is a TMDS/HDMI 3:1 switch with signal equalizer. The device is a HDMI
switch featuring an integrated 4-channel 3.4 Gbps TMDS equalizer and 3:1 switch to select
one of the three HDMI ports (either external ports or internal sources).
The high-speed data paths and flow-through pinout minimize the internal device jitter and
simplify the board layout.
The equalizer provides compensation to overcome the intersymbol interference (ISI) jitter
effects from lossy cables.
The output driver buffers the TMDS output signals over long distances.
Also, the STDVE103A integrates the 50 Ω termination resistor on all the input channels to
improve performance and reduce board space.
The device can operate in a low-power mode by disabling the output current drivers.
The STDVE103A is ideal for advanced TV and STB applications supporting the HDMI/DVI
standard. 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.
The STDVE103A provides the ability to boost the incoming TMDS signal and drive it to a
level which allows efficient signal recovery at the HDMI receiver. It is especially useful for
boosting signals for longer distance transmission when the HDMI receiver is physically
distant from the HDMI input port.
