ABSOLUTE MAXIMUM RATINGS

BACKLIGHT AND FAN1 CRITERIA

SPECIFICATION

Backlight PWM2 Frequency

320 Hz nominal

Fan Tachometer Speed Range (assuming

two PPR3)

600 RPM to 3,000,000 RPM

Fan Power Control PWM2 Frequency

18 Hz nominal

1Fans are an optional accessory.

2PWM is Pulse Width Modulation. PWM is a way to simulate intermediate levels by switch-

ing a level between full on and full off. PWM can be used to control the brightness of LED

backlights, relying on the natural averaging done by the human eye, as well as for control-

ling fan power.

3PPR is Pulses Per Revolution, also written as p/r.
