YSD221

      The YSD221(DIT3) is an LSI which outputs the digital sound singnals as digital audio interface (DIF) singnals that conform to EIAJ CP-340 and AES/EBU.It also has a function of multiplexing with DIF singals from the CD singal processing LSI.Use of YSD221 in combination with YM7110(LVFM) enables sound singals from the multi-disc player to be fully digitized,peripheral circuits,sound singals to be switched and bilinguar processed as well.
      The YSD221(DIT3) has 8 features.The first one is synchronous operations with the external clock (384fs) inputted into the MCLK terminal.The second one is capable of accepting synchronized DIF singals in addition to the digital sound signals.The third one is usable for bilingual discs as any input channel signals can be switched to thre output channel.The fourth one is outputs input signals as bit-plase signal. The fifth one is first 32 bit of the channel status can be set through microprocessor.The sixth one is also outputs signals to be digital filter,etc.The seventh one is 5V signal power supply,si-gate CMOS process.The eighth one is 16 pin SOP or 16 pin DIP.
      The YSD221(DIT3) has some information about electrical characteristics.The absolute maximum rating:when parameter is power supply voltage,the symbol is VDD,the rating is -0.3-7.0,the unit is V.when parameter is input voltage,the symbol is VI,the rating is -0.3-VDD+0.3,the unit is V.when parameter is operating temperature,the symbol is Top,the rating is 0-70,the unit is °C.when parameter is storage temperature,the symbol is Tstg,the rating is -50-125,the unit is °C.
      At present there is not too much information about this model.If you are willing to find more  about the YSD221(DIT3), please pay attention to our web! We will promptly update the relevant  information.
