3.3.5 IR Receiver
The SCD provides an infrared remote-control receiver Module (model: IRM-V538N7/TR1), whose
datasheet is offered in the directory \Datasheet\IR_Receiver on the SCD System CD. Note that for
this all-in-one receiver module, it is only compatible with the 38KHz carrier Standard, with a
maximum data rate of about 4kbps for its product information. The accompanied remote controller
with an encoding chip of uPD6121G is very suitable of generating expected infrared signals.
Figure 3-8 shows the related schematic of the IR receiver, and the pin assignments of the associated
interface connected to DE0-Nnao GPIO0 are listed in Table 3-6 .
