Power Consumption
The IsoLoop family of devices achieves its low power
consumption from the manner by which it transmits data
across its isolation barrier. By detecting the edge transitions
of the input logic signal and converting this to a narrow
current pulse which drives the isolation barrier, the isolator
then latches the input logic state in the output latch. Since
the current pulses are narrow, about 2.5 ns wide, the power
consumption is independent of mark-to-space ratio and
solely dependent on frequency. This has obvious advantages
over optocouplers whose power consumption is heavily
dependent on its on state and frequency.
Power Supply Decoupling
Both power supplies to these devices should be decoupled
with good quality 47 nF ceramic capacitors. For data
rates in excess of 10MBd, use of ground planes for both
GND1 and GND2 is highly recommended. Capacitors
should be located as close as possible to
the device.
Signal Status on Start-up and Shut Down
To minimize power dissipation, the input signals to the
IL715, IL716 and IL717 are differentiated and then latched
on the output side of the isolation barrier to reconstruct the
signal. This could result in an ambiguous output state
depending on power up, shutdown and power loss
sequencing. Therefore, the designer should consider the
inclusion of an initialization signal in his start-up circuit.
Data Transmission Rates
The reliability of a transmission system is directly related to
the accuracy and quality of the transmitted digital
information. For a digital system, those parameters which
determine the limits of the data transmission are
pulse width
distortion
and
propagation delay skew
.
Propagation delay is the time taken for the signal to travel
through the device. This is usually different when sending a
low-to-high than when sending a high-to-low signal. This
difference, or error, is called pulse width distortion (PWD)
and is usually in ns. It may also be expressed as a
percentage:
This figure is almost
3x
better than for any available
optocoupler with the same temperature range, and
2x
better
than any optocoupler regardless of published temperature
range. The
IsoLoop
range of isolators including the IL717
surpasses the 10% maximum PWD recommended by
PROFIBUS, and will run at almost 35 Mb before reaching
the 10% limit.
Propagation delay skew is the difference in time taken for
two or more channels to propagate their signals. This
becomes significant when clocking is involved since it is
undesirable for the clock pulse to arrive before the data has
settled. A short propagation delay skew is therefore critical,
especially in high data rate parallel systems, to establish and
maintain accuracy and repeatability. The
IsoLoop
range
of isolators all have a maximum propagation delay skew of
6 ns, which is
5x
better than any optocoupler. The
maximum channel to channel skew in the IL717, IL716, and
IL715 isolators is only 3 ns which is
10x
better than any
optocoupler.
Application Notes:
PWD% =
Maximum Pulse Width Distortion (ns)
Signal Pulse Width (ns)
x 100%
e.g. for the
IL717
@ 12.5 Mb
PWD% =
3 ns
80 ns
x 100% =
3.75%
