Adaptive 3.4 Gbps 3:1 TMDS/HDMI signal equalizer

STMicroelectronics STDVE003AThe 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 Ω 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.
