GP2W0001YP/GP2W0002YP
Signal Waveform Example
Figure 14 shows examples of each waveform when
operating a GP2W0001YP to IrDA standards. Note that
the IrDA bitstream is inverted in the encoder and
decoder circuits, and the output pulse is sent during a
‘0’ bit. The examples are for reference only, to help
understand the GP2W0001YP hardware, and device
signal measurements. The receiver output is not gated,
and will send output for the entire period of the received
IR input signal. Refer to Figure 14 for waveform refer-
ence points.
