Notes
• Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing
(1)
IrDA specification is 40 mW/m
2
. Specification takes a window loss of 10 % into account
(2)
IrDA sensitivity definition: minimum irradiance E
e
in angular range, power per unit area. The receiver must meet the BER specification while
the source is operating at the minimum intensity in angular range into the minimum half-angular range at the maximum link length
(3)
Maximum irradiance E
e
in angular range, power per unit area. The optical delivered to the detector by a source operating at the maximum
intensity in angular range at minimum link length must not cause receiver overdrive distortion and possible ralated link errors. If placed at
the active output interface reference plane of the transmitter, the receiver must meet its bit error ratio (BER) specification
(4)
Using an external current limiting resistor is allowed and recommended to reduce IRED intensity and operating current when current
reduction is intended to operate at the IrDA low power conditions. E.g. for V
CC2
= 3.3 V a current limiting resistor of R
S
= 56 Ω will allow a
power minimized operation at IrDA low power conditions
(5)
Due to this wavelength restriction compared to the IrDA spec of 850 nm to 900 nm the transmitter is able to operate as source for the
standard remote control applications with codes as e.g. Phillips RC5/RC6
®
or RECS 80
