Description

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 three input HDMI ports

can be either external ports or internal sources.

High-speed data paths and flow-through pin-out

minimize internal device jitter and simplify board

layout. The equalizer overcomes 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

input channels to improve performance and

reduce board space. The device can be put in a

low-power mode by disabling the output current

drivers.

The STDVE003A is ideal for advanced HDTV

applications demanding HDMI deep colour (16-

bit) superior image quality. The switch preserves

the signal integrity to pass the stringent HDMI

compliance requirements.
