Remote Control Operation
The ASDL-3007 is spectrally suited to universal remote
control transmission function. Remote control applica-
tions are not governed by any standards, owing to which
there are numerous remote codes in market. Each of
those standards results in receiver modules with different
sensitivities, depending on the carries frequencies and
responsively to the incident light wavelength.
Figure C3 illustrate a reference interfacing circuit to
implement both IrDA and RC functionality using ASDL-
3007. The transceiver is directly interface with the micro-
processor provided it has support for infrared commu-

nication commonly known as Infrared Communications
Port (ICP). The remote control commands can be sent
through one of the available General Purpose IO pins
(GPIO). It is not recommended to turn on both IrDA data
transmission and Remote control transmission simulta-
neously to prevent mixing and corruption of data. During
IrDA data transmission, TxD_RC pin should be pull-down
but not letting it floating. Same condition applied for
Remote control transmission, which TxD_IR pin should
not be left floating.
