Description

The AD8134 is a major advancement beyond using discreteop amps for driving differential RGB signals over twisted paircable. The AD8134 is a triple, low cost differential or single-endedinput to differential output driver, and each amplifier hasa fixed gain of 2 to compensate for the attenuation of the linetermination resistors. The AD8134 is specifically designed forRGB signals but can be used for any type of analog signals orhigh speed data transmission. The AD8134 is capable of drivingeither Category 5 (Cat-5) unshielded twisted pair (UTP) cableor differential printed circuit board transmission lines withminimal signal degradation.A unique feature that allows the user to transmit balancedhorizontal and vertical video sync signals over the threecommon-mode channels with minimal electromagneticinterference (EMI) radiation is included on-chip.The outputs of the AD8134 can be set to a low voltage state thatallows easy differential multiplexing of multiple drivers on thesame twisted pair cable, when used with external series diodes.The AD8134 driver is a natural complement to the AD8143,AD8129, and AD8130 differential receivers.Manufactured on the Analog Devices next generation XFCBbipolar process, the AD8134 has a large signal bandwidth of225 MHz and a slew rate of 1600 V/?s. The AD8134 has aninternal common-mode feedback feature that provides outputgain and phase matching that is balanced to ?60 dB at 50 MHz,suppressing harmonics and reducing radiated EMI.The AD8134 is available in a 24-lead LFCSP and can operateover the ?40?C to +85?C extended industrial temperature range.Applications Keyboard-video-mouse (KVM) networking
