Description
The STDVE001A integrates a 4-channel 3.4 Gbps TMDS equalizer. High-speed data paths and flowthrough pinout minimize the internal device jitter and simplify the board layout.
The equalizer overes 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, STDVE001A 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 STDVE001A 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 STDVE001A to guarantee good signal quality at the HDMI...
