Differential Video Interface Chipset  
General Description  
Features  
The MAX9546/MAX9547 differential interface chipset  
converts single-ended voltages to differential voltages for  
transport and then converts back to single-ended volt-  
ages. These devices eliminate costly, bulky, single-  
ended coaxial cables with inexpensive, readily available,  
differential shielded (ScTP) or unshielded (UTP) twisted  
pairs. The fault detection of the MAX9546 and loss-of-sig-  
nal detection of the MAX9547 allow proactive and  
speedy diagnosis, such as identifying failures in the man-  
ufacturing stage and troubleshooting equipment at repair  
facilities. The MAX9546/MAX9547 are low-cost, conve-  
nient solutions for transporting CVBS/FBAS analog video  
signals (PAL or NTSC) through hostile environments.

The MAX9546 driver converts the single-ended input into  
a differential output with a 6dB fixed gain to drive a back-  
terminated, DC-coupled differential video output to unity  
gain. This DC connection allows the detection of a short-  
circuit condition at the differential outputs. The FAULT  
output indicates a short-circuit condition including a

Driver  
The MAX9547 receiver converts the differential signal  
from the MAX9546 into a single-ended signal. Like the  
MAX9546 output, the MAX9547 input survives a short to  
a high battery condition or ground. The MAX9547 receiv-  
er loss-of-signal output (LOS) operates by detecting the  
H-Sync and thus can support both monochrome and  
color video signals. The MAX9547 gain is set with an  
external impedance between ZT+ and ZT-.

The MAX9546/MAX9547 operate from a 7.5V to 10V  
single supply. Both devices include 15kV ꢀSD Human  
Body Model (HBM) protection. The MAX9546/MAX9547  
are offered in a thermally enhanced 8-pin SO package  
and specified over the -40°C to +85°C extended tem-  
perature range.
