Differential Video Interface Chipset
The MAX9546/MAX9547 differential interface chipset
converts single-ended voltages to differential voltages
for transport and then converts back to single-ended
voltages. The chipset is optimized for transporting
CVBS/FBAS analog video signals (PAL or NTSC)
through hostile automotive environments. The
MAX9546 driver includes a fault output (FAULT) that
indicates shorted transmission cables. The MAX9547
receiver loss-of-signal output (LOS) indicates an
absence of input signal.
The MAX9546/MAX9547 operate from a 7.5V to 10V sin-
gle supply. The differential interface is immune to short-
circuit conditions to an automotive battery (V

ESD (Human Body Model) protection.
The MAX9546 driver converts a single-ended video
input into a differential output for transport across a
twisted pair of wires. The input is AC-coupled and the
video signal sync tip is clamped at 3.46V to set the
voltage of the input. The output common-mode voltage
is optimized to reject ground differences between the
MAX9546 and MAX9547 up to ±2V. The differential
gain is internally set to 2V/V to drive a back-terminated
output to unity gain. The maximum input resistance
should not exceed 400Ω to ensure device stability.
