LIU Interface Recommendations
The MAX4670 low 0.7
(typ) on-resistance is ade-
quate, even in applications where the LIUs require no
external series transmit resistors (Rt = 0 in Figures 8
and 10). However, in some instances, increase the LIU
output amplitude to compensate for R
ON
if the LIU sup-
ports programmable output amplitude. With LIUs
requiring external transmit resistors, it is recommended
to reduce Rt by the amount of the typical R
ON
with LIUs
requiring external transmit resistors.
For example, if the LIU vendor recommends Rt = 9.1
,
the actual value in the application should be:
Rt = Rt
–
R
ON
= 9.1
- 0.7 = 8.4
The receive interface series resistance is small enough
to support LIUs with internal line termination, provided
the external 120
parallel resistor combination (Rr) is
connected, as shown in Figures 7 and 9.
While in normal operation, the MAX4670 requires the
input and output signals to be within the V+ and GND
supply rails.
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 11 shows the Human Body Model. Figure 12
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 interest,
which is then discharged into the test device through a
1.5k
resistor.
IEC 1000-4-2
The IEC 1000-4-2 standard covers ESD testing and
performance of finished equipment. It does not specifi-
cally refer to ICs. The major difference between tests
done using the Human Body Model and IEC 1000-4-2
is a higher peak current in IEC 1000-4-2, because
series resistance is lower in the IEC 1000-4-2 model.
Hence, the ESD withstands voltage measured to IEC
61000-4-2, and is generally lower than that measured
using the Human Body Model. Figure 13 shows the IEC
61000-4-2 model, and Figure 14 shows the current
waveform for the ±8kV IEC, 61000-4-2 Level 4, ESD
Contact Discharge test. The Air-Gap test involves
approaching the device with a charged probe. The
Contact Discharge method connects the probe to the
device before the probe is energized.
Machine Model
The Machine Model for ESD tests all pins using a
200pF storage capacitor and zero discharge resis-
tance. Its objective is to emulate the stress caused by
contact that occurs with handling and assembly during
manufacturing.
