General Description
RTS3351C is a dual channel voice synthesizer. The dual tone voice melody is generated
through programming the sampling rates. There are two kinds of instruments which can be
simultaneously played out with sustainable voice, therefore, using small voice-ROM size,
RTS3351C can achieve real instrument effects (especially instruments that need sustainable
voice). Multiple musical instrument effects (more than 2 channels) are achieved by combining
two chips together to perform 4-channel voice melody. RTS3351C also provides 2
programmable output drivers (MT1 & MT2) and 4 LED outputs for various applications.
