AD8143:  High Speed, Triple Differential Receiver with Comparators

Product Description

The AD8143 is a triple, low cost, differential-to-single-ended receiver specifically designed for receiving red-green-blue (RGB) signals over twisted pair cable. It can also be used for receiving any type of analog signal or high speed data transmission. Two auxiliary comparators are provided to receive digital or sync signals. The AD8143 can be used in conjunction with the AD8133 and AD8134 triple, differential drivers to provide a complete low cost solution for RGB over Category-5 unshielded twisted pair (UTP) cable applications, including keyboard-video-mouse (KVM).

The excellent common-mode rejection (65 dB @ 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. Closed-loop gain is easily set using external resistors.

The AD8143 is available in a 5 mm x 5 mm, 32-lead LFCSP and is rated to work over the extended industrial temperature range of -40°C to +85°C.
