Products - GPRC201A


Encode/Decode functionFunctionsR-OSCRF-OSCRF Power AmplifierData in amplifierDC-DC

General Description

These two devices are designed for encoder and decoder as pairs in remote control applications. The GPRC201A is a remote control encoder that encodes 10 lines of binary information into serial bit-stream data. When any of the 10 lines of information is activated, RF will be enabled or an infrared transmission medium will transmit encoded bit-stream data. After the 10 lines of information become inactive, the GPRC201A will transmit additional five data frames to improve transmitting reliability.
In contrast, the GPRC202A is a remote control decoder, which decodes the received serial bit-stream data from the GPRC201A and interprets 10 lines of information as 10 bits output data to control the corresponding external component. The GPRC202A provides nine types of momentary and one toggle types of outputs. The GPRC202A will be activated only when two consecutive and equal frames are received.
