The AD8145 is a triple, low cost, differential-to-single-ended receiver specifically designed for receiving red-green-blue (RGB) video signals over twisted pair cable or differential printed circuit board traces. It can also be used to receive any type of analog signal or high speed data transmission. Two auxiliary comparators with hysteresis are provided, which can be used to decode video sync signals that are encoded on the received common-mode voltages, to receive digital signals, or as general-purpose comparators. The AD8145 can be used in conjunction with the AD8133 or AD8134 triple differential drivers to provide a complete low cost solution for RGB over Category 5 UTP cable applications, including KVM.
The excellent common-mode rejection (69 dB @ 10 MHz) of the AD8145 allows for the use of low cost, unshielded twisted pair cables in noisy environments.
