GENERAL DESCRIPTION
The ADV3002 is a complete HDMI™/DVI link switch featuring
equalized transition minimized differential signaling (TMDS)
inputs, ideal for systems with long cable runs. The ADV3002
includes bidirectional buffering for the DDC bus and CEC line,
with integrated pull-up resistors for the CEC line. Additionally,
the ADV3002 includes an EDID replication function that enables
one EDID EEPROM to be shared for all four HDMI ports.
The ADV3002 is provided in a space-saving, 80-lead LQFP
surface-mount, Pb-free plastic package and is specified to
operate over the 0°C to 85°C temperature range.
1. Input cable equalizer enables use of long cables at the input.
For a 24 AWG cable, the ADV3002 compensates for more
than 15 meters at data rates of up to 3 Gbps.
2. Auxiliary multiplexer isolates and buffers the DDC bus and
the CEC line, increasing total system capacitance limit.
3. EDID replication eliminates the need for multiple EDID
EEPROMs. EDID can be loaded from a single external
EEPROM or from a system microcontroller.
4. 5 V power combiner powers the EDID replicator and CEC
buffer when local system power is off.
5. Integrated hot plug detect pulse low on channel switch
with programmable pulse width or direct manual control.
