3:1 TMDS / HDMI signal equalizer
Data Brief
Compatible with HDMI v1.3 digital interface
www.DataSheet4U.comConforms to the TMDS voltage standard on
input and output channels
340 MHz maximum clock speed operation
enabling up to 3.4 Gbps data rate per channel
Integrated open-drain I2C buffer for DDC lines
5.3 V tolerant I2C I/O with 0 to 400 kHz
Ultra low capacitance of the channels
Equalizer regenerates the incoming attenuated
TMDS signal
Buffer drives the TMDS outputs over long PCB
track lengths
Very low output skew and jitter
Tight input thresholds reduce bit error rates
On-chip 50 Ω input termination
Integrated fail-safe feature sets outputs to
known state for un-driven inputs
Available in TQFP80 package footprint with
flow-through pin-out
-40°C to 85°C operating temperature range
Evaluation kit and samples are available
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
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.
