GENERAL DESCRIPTION
The AD8143 has a wide power supply range from single +5 V The AD8143 is a triple, low cost, differential-to-single- supply to ±12 V, which allows for a wide common-mode range. ended receiver specifically designed for receiving red- The wide common-mode input range of the AD8143 maintains green-blue (RGB) signals over twisted pair cable. It can signal integrity in systems where the ground potential is a few also be used for receiving any type of analog signal or volts different between the drive and receive ends without the high speed data transmission. Two auxiliary comparators use of isolation transformers. are provided to receive digital or sync signals. The The AD8143 is stable at a gain of 1. Closed-loop gain is easily AD8143 can be used in conjunction with the AD8133 set using external resistors. and AD8134 triple, differential drivers to provide a complete low cost solution for RGB over Category-5 The AD8143 is available in a 5 mm × 5 mm, 32-lead LFCSP and UTP cable applications, including KVM. is rated to work over the extended industrial temperature range of −40°C to +85°C. The excellent common-mode rejection (65 dB at 10 MHz) of the AD8143 allows for the use of low cost unshielded twisted pair cables in noisy environments.
