Notes:
1. 2.2nF cap is optional and should be placed close to the EMC6D103 if used.
2. The voltage at PWM3 must be at least 2.0V to avoid triggering Address Enable.
3. The Remote Diode + and Remote Diode - tracks should be kept close together, in parallel with
grounded guard tracks on each side. Using wide tracks will help to minimize inductance and
reduce noise pickup. A 10 mil track minimum width and spacing is recommended. See Figure B.5,
"Suggested Minimum Track Width and Spacing".
