Introduction

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.

Features

• 4 inputs, 1 output HDMI/DVI links
• ±8 kV ESD protection on input pins
• HDMI 1.4a receive and transmit compliant
• Supports 250 Mbps to 2.25 Gbps data rates and beyond
• Supports 25 MHz to 225 MHz pixel clocks and beyond
• Fully buffered unidirectional inputs/outputs
• Switchable 50 Ω on-chip input terminations with manual or automatic control on channel switch
• Equalized inputs with low added jitter compensate for more than 20 meters of HDMI cable at 2.25 Gbps
• Loss of signal (LOS) detect circuit on TMDS clock
• Output disable feature for reduced power dissipation
• Bidirectional DDC buffers (SDA and SCL)
• EDID replication reduces component count, while enabling simultaneous access to all HDMI sources
