Data Sheet
PROPAGATION DELAY-RELATED PARAMETERS
Propagation delay is a parameter that describes the time it takes
a logic signal to propagate through a component. The propaga-
tion delay to a logic low output may differ from the propagation
delay to a logic high output.

Figure 18. Propagation Delay Parameters
Pulse width distortion is the maximum difference between
these two propagation delay values and is an indication of how
accurately the timing of the input signal is preserved.
Channel-to-channel matching refers to the maximum amount
that the propagation delay differs between channels within a
single ADuM6132 component.
MAGNETIC FIELD IMMUNITY
The ADuM6132 is extremely immune to external magnetic
fields. The limitation on the ADuM6132 magnetic field immunity
is set by the condition in which induced voltage in the receiving
coil of the transformer is sufficiently large to falsely set or reset
the decoder. The following analysis defines the conditions
under which this may occur.
The pulses at the transformer output have an amplitude greater
than 1.0 V. The decoder has a sensing threshold at approximately
0.5 V, thus establishing a 0.5 V margin in which induced voltages
can be tolerated. The voltage induced across the receiving coil is
given by
V = (? dβ / dt ) Σπ r n 2 ; n = 1, 2, … N

MAGNETIC FIELD FREQUENCY (Hz)
Figure 19. Maximum Allowable External Magnetic Flux Density
For example, at a magnetic field frequency of 1 MHz, the
maximum allowable magnetic flux density of 0.2 kgauss
induces a voltage of 0.25 V at the receiving coil. This voltage
is approximately 50% of the sensing threshold and does not
cause a faulty output transition. Similarly, if such an event
occurs during a transmitted pulse (with the worst-case polarity),
the received pulse is reduced from >1.0 V to 0.75 V—still well
above the 0.5 V sensing threshold of the decoder.
The preceding magnetic flux density values correspond to
specific current magnitudes at given distances from the
ADuM6132 transformers. Figure 20 expresses these allowable
current magnitudes as a function of frequency for selected
distances. As shown in Figure 20, the ADuM6132 is extremely
immune and can be affected only by extremely large currents
operated at high frequency and very close to the component.
For example, at a magnetic field frequency of 1 MHz, a 0.5 kA
current would need to be placed 5 mm away from the ADuM6132
to affect the operation of the component.
β is the magnetic flux density (gauss).
r n is the radius of the nth turn in the receiving coil (cm).
N is the number of turns in the receiving coil.
Given the geometry of the receiving coil in the ADuM6132 and
an imposed requirement that the induced voltage be at most
50% of the 0.5 V margin at the decoder, a maximum allowable
magnetic flux density is calculated, as shown in Figure 19.
