| High-Speed Triple Differential Receiver with Comparators Preliminary Technical Data FEATURES High Speed 300MHz, 1000V/ s @ G = 1, VO = 1 V P-P High CMRR: 70dB @ 10MHz High Differential Input Impedance: 6M Imput Common Mode Range: 10 V ( 12 V Supplies) User Adjustable Gain Wide Power Supply range: + 4.5V to 12V Fast Settling: 2ns to 1%, 5 ns to 0.1% Low Noise: 12 nV/ Hz Small Packaging: 32-Pin 5 x 5 mm LFCSP Package AD8143 PINOUT DIAGRAM APPLICATIONS RGB Video Receiver KVM (Keyboard-Video-Mouse) UTP (Unshielded Twisted Pair) Receiver GENERAL DESCRIPTION The AD8143 is a triple, low cost differential to single ended receiver specifically designed for receiving RGB (red-greenblue) signals over twisted pair cable but can also be used for receiving any type of analog signal or high speed data transmission. Two auxiliary comparators are also provided to receive digital or sync signals. The AD8143 can be used in conjunction with the AD8133 triple, differential driver to provide a complete low cost solution for RGB over Category5 unshielded twisted pair (UTP) cable applications including KVM (keyboard-video-mouse). The excellent common-mode rejection (60dB @ 10 MHz) of the AD8143 allows for the use of low cost unshielded twisted pair cables in noisy environments. The AD8143 has a wide power supply range from single 5 V supply to 12 V, which allows for a wide common-mode range. The wide common mode input range of the AD8143 maintains signal integrity in systems where the ground potential is a few volts different between the drive and receive ends without the use of isolation transformers. The AD8143 is stable at a gain of 1. The closed-loop gain can easily be set by external resistors. The AD8143 is available in a 5 mm x 5 mm 32 lead LFCSP package and is rated to work over the extended industrial temperature range, -40C to +85C. Rev.
