Applications Information
Differential Interface
The impedances of the differential interface are made
up of the two source resistors on the driver (MAX9546)
shown as R
S
and the load resistors on the receiver
(MAX9547) shown as R
T
in the
Typical Application
Circuit.
These resistors are chosen so their sum match-
es the characteristic impedance (Z
0
) of the differential
transmission line. For example, a Category 5 cable has
a characteristic impedance of 110
, so the sum of the
two R
S
or R
T
resistors must be 110
to correctly drive
the line. To balance the signals they must be equal, so
R
S
and R
T
are 55
each.
±15kV ESD Protection
As with all Maxim devices, ESD-protection structures
are incorporated on all pins to protect against electro-
static discharges encountered during handling and
assembly. The driver outputs and receiver inputs have
extra protection against static electricity. Maxim’s engi-
neers developed state-of-the-art structures to protect
these pins against ESD of ±15kV without damage. The
ESD structures withstand high ESD in all states: normal
operation and powered down. After an ESD event, the
MAX9546/MAX9547 keep working without latchup. ESD
protection can be tested in various ways; the driver out-
puts and receiver inputs of this product family are char-
acterized for protection to ±15kV using the Human
Body Model. Other ESD test methodologies include IEC
1000-4-2 Contact Discharge and IEC 1000-4-2 Air-Gap
Discharge (formerly IEC 801-2).
ESD Test Conditions
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents
test setup, test methodology, and test results.
Human Body Model
Figure 2 shows the Human Body Model, and Figure 3
shows the current waveform it generates when dis-
charged into a low impedance. This model consists of
a 100pF capacitor charged to the ESD voltage of inter-
est, which is then discharged into the test device
through a 1.5k
resistor.
