Remote Control Operation
The HSDL-3021 is spectrally
suited to universal remote
control transmission function at
940 nm typically. Remote control
applications 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
Table 3.

carrier frequencies and
responsively to the incident light
wavelength. Remote control
carrier frequencies are in the
range of 30 KHz to 60 KHz (for
details of some the frequently
used carrier frequencies, please
refer to AN1314). Some common
carrier frequencies and the
corresponding SA-1110 UART
frequency and baud rate divisor
are shown in Table 3.
