3:1 TMDS / HDMI signal equalizer
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.
