GENERAL DESCRIPTION

The AD8141 and AD8142 are triple, low cost, differential or  
single-ended-input-to-differential-output drivers. Each amplifier  
has a fixed gain of 2 to compensate for the attenuation of the  
line termination resistors. The AD8141 and AD8142 are  
specifically designed for RGB signals but can be used for any  
type of signals. The amplifiers have very fast slew rate and  
settling time while being manufactured on a cost effective  
CMOS process. They are optimized for high resolution video  
performance with a 0.1 dB flatness of 65 MHz, which allows  
driving high resolution video over any type of UTP cable.  
Figure 2.  
The AD8142 includes a unique sync-on-common-mode feature  
that allows the user to transmit balanced horizontal and vertical  
video sync signals over the three common-mode channels.  
Additionally, the AD8141 and AD8142 both have a disable  
feature that, when asserted, produces high-Z outputs, allowing  
line isolation and easy multiplexing.  
The drivers have an internal common-mode feedback loop  
that provides output amplitude and phase matching, achieving  
−50 dB balance error at 50 MHz and thereby suppressing even-  
order harmonics and minimizing radiated electromagnetic  
interference (EMI).  
The AD8141 and AD8142 are available in a 24-lead 4 mm × 4 mm  
LFCSP and operate over a temperature range of −40°C to +85°C.  
They can be used with the AD8145 triple differential-to-single-  
ended receiver, AD8123 triple equalizer, AD8120 triple delay  
line, and the AD8117 or AD8175 crosspoint switches to produce  
a high resolution video distribution system.
