STDVE003A
3:1 TMDS / HDMI signal equalizer
Data Brief
Features
■ 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
frequency
■ 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

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.
