AD8134:  Triple Differential Driver With Sync-On-Common-Mode

The AD8134 is a major advancement beyond using discrete op amps for driving differential RGB signals over twisted pair cable. The AD8134 is a triple, low cost differential or single-ended input to differential output driver, and each amplifier has a fixed gain of 2 to compensate for the attenuation of the line termination resistors.

AD8134:  Triple Differential Driver With Sync-On-Common-Mode

Product Description

The AD8134 is a major advancement beyond using discrete op amps for driving differential RGB signals over twisted pair cable. The AD8134 is a triple, low cost differential or single-ended input to differential output driver, and each amplifier has a fixed gain of 2 to compensate for the attenuation of the line termination resistors. The AD8134 is specifically designed for RGB signals but can be used for any type of analog signals or high speed data transmission. The AD8134 is capable of driving either Category 5 (Cat-5) unshielded twisted pair (UTP) cable or differential printed circuit board transmission lines with minimal signal degradation.

A unique feature that allows the user to transmit balanced horizontal and vertical video sync signals over the three common-mode channels with minimal electromagnetic interference (EMI) radiation is included on-chip.

The AD8134 is available in a 24-lead LFCSP and can operate over the -40°C to +85°C extended industrial temperature range.
