ADV3002:  4:1 HDMI/DVI Switch with Equalization DDC/CEC Buffers and EDID Replication

Product 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.

Product Highlights

  1. Input cable equalizer enables use of long cables at the input. For a 24 AWG cable, the ADV3002 compensates for more than 20m at data rates up to 2.25 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.
