The STDVE003A integrates a 4-channel 3.4 Gbps TMDS equalizer and a 3:1 switch to select one of the three HDMI ports. The 3-input HDMI ports can be either external ports or internal sources. Highspeed data paths and flow-through pinout minimize the internal device jitter and simplify the board layout. The equalizer overcomes the intersymbol interference (ISI) jitter effects from lossy cables. The buffer/driver on the output can drive the TMDS output signals over long distances. In addition to this, STDVE003A integrates the 50 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 STDVE003A is ideal for advanced TV and STB applications supporting HDMI/DVI standard. The differential signal from the HDMI/DVI ports can be routed through the STDVE003A 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.
