GENERAL DESCRIPTION  
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 AD8145 can be configured for a differential-to-single-  
ended gain of 1 or 2 by connecting the GAIN pin of each  
channel to its respective output (G = 1) or connecting it to a  
reference voltage (G = 2), which is normally grounded.  
A REF input is provided on each channel that allows designers  
to level shift the output signals.  
The AD8145 is available in a 5 mm × 5 mm, 32-lead LFCSP and  
is rated to work over the extended industrial temperature range  
of −40°C to +105°C.  
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.
