The AD8143 reduces board space by up to 60 percent for keyboard-video-mouse (KVM) and video-over-Category-5 applications
Analog Devices is introducing a triple differential receiver, the AD8143, that offers a compact single-chip solution for receiving differential signals over twisted pair cable. The AD8143 is primarily designed to receive RGB (red-green-blue) signals having resolutions up to 1600 x 1200; however, it can also be used to receive any other type of differential analog signal or high-speed data transmission. When compared with multi-chip solutions, the AD8143 reduces board space by up to 60 percent and decreases costs by as much as 45 percent.In addition to the three differential receivers, the AD8143 includes two auxiliary comparators, which can be used to receive digital signals from the fourth twisted pair of the Cat-5 cable, such as keyboard or mouse functions in KVM applications.
The AD8143 complements Analog Devices' AD8133, the industry's smallest triple differential line driver specifically designed for driving RGB signals over Cat-5 cables. Paired together, the AD8143 and AD8133 offer a complete solution for transporting video over twisted pair cable.
Pricing and Availability
The AD8143 triple differential receiver operates over the temperature range of -40 degrees Celsius to +85 degrees Celsius and is available in a 5 mm x 5 mm, 32-pin LFCSP (lead frame chip scale package) for increased board space savings. The AD8143 is priced at $2.55 per unit in 1,000 unit quantities.
