MAX9546/MAX9547
Differential Video Interface Chipset

______________________________________________________________________________________
Applications Information
Differential Interface
The impedances of the differential interface are made
up of the two source resistors on the driver (MAX9546)
shown as RS and the load resistors on the receiver
(MAX9547) shown as RT in the Typical Application
Circuit. These resistors are chosen so their sum match-
es the characteristic impedance (Z0) of the differential
transmission line. For example, a Category 5 cable has
a characteristic impedance of 110, so the sum of the
two RS or RT resistors must be 110 to correctly drive
the line. To balance the signals they must be equal, so
RS and RT are 55 each.
Using Other Transmitters
and Receivers
The MAX9546/MAX9547 are used with other transmit-
ters and receivers; either other MAXIM devices or other
brands entirely. The overall performance of the
MAX9546/MAX9547 is dependent on the choice of the
receiver or transmitter, respectively.
Figure 2 illustrates one possible topology for the
MAX9546 when using other devices with different offset
requirements. Figures 3 and 4 illustrate two possible
topologies for the MAX9547 when using other devices
with unknown or different offset requirements. The cir-
cuit shown in Figure 3 has a smaller PCB footprint at
the expense of requiring higher DC offset currents from
the source device. Figure 4 requires no DC offset cur-
rents although it has a larger PCB footprint.
When using the MAX9546 with AC-coupling capacitors,
the FAULT signal will continue to function but only with
respect to a DC short condition. The LOS signal from
the MAX9547 is unaffected by coupling capacitors.
