Datasheet
SMSC SCH311X
Notes:
1. 2.2nF cap is optional and should be placed close to the SCH311X f 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".
