tion while the source is operating at the minimum intensity in angular range into the minimum half-angle range at the maximum Link Length.
***)
maximum intensity in angular range at Minimum Link Length must not cause receiver overdrive distortion and possible related link errors.
If placed at the Active Output Interface reference plane of the transmitter, the receiver must meet its bit error ratio (BER) specification.
For more definitions see the document “Symbols and Terminology” on the Vishay Website (http://www.vishay.com/docs/82512/82512.pdf).

TFBS5700 is set to the "short output pulse" as default after power on, also after recovering from the shutdown mode (SD must have been
longer active than 1.5 ms). For mode changing see the chapter "Programming".

This parameter reflects the backlight test of the IrDA physical layer specification to guarantee immunity against light from fluorescent
Some ENDECs are not able to decode short pulses as valid SIR pulses. Therefore this additional mode was added in TFBS5700.
