Fig.10 Reset Function
Fig.11 Peak Forward Current vs. Ambient
The “RESET” terminal is used to recover the receiver sensitivity to its maximum level.
Sharp IrDA control Transceiver has a built-in capability to adjust the receiver sensitivity (Threshold level adjustment).With
this function, in order to receive very weak infrared signals right after very strong infrared signals, following input to
“RESET” terminal provides the receiver sensitivity recovery to its maximum level.
RESET INPUT (High level input voltage 2.1V V
The RESET input must be pulsed to the transcever within the gap time for correct operation.
The timing for “RESET” must be adjusted at the controlled IC.
