Electrostatic Discharge Sensitivity
The RM912 is a Class I device.
Figure 21
lists the Electrostatic Discharge (ESD) immunity level
for each pin of the RM912 product. The numbers in
Figure 21
specify the ESD threshold level for
each pin where the I-V curve between the pin and ground starts to show degradation. The ESD
testing was performed in compliance with MIL-STD-883E Method 3015.7 using the Human Body
Model. Since 2000 volts represents the maximum measurement limit of the test equipment used,
pins marked > 2000 V pass 2000V ESD stress.
Various failure criteria can be utilized when performing ESD testing. Many vendors employ
relaxed ESD failure standards which fail devices only after
“
the pin fails the electrical specification
limits
”
or
“
the pin becomes completely non-functional
”
. Conexant employs most stringent criteria,
fails devices as soon as the pin begins to show any degradation on a curve tracer.
To avoid ESD damage, latent or visible, it is very important the Class-1 ESD handling precautions
listed in
Table 6
be used in the product assembly and test areas follow.
