YSES14K, YSES18K, YSF210B

      The YSF210B(OSF22) is a high grade digital filter capable of 22-bit, 8-times oversampling in two channels.Like the YM3434 and YM3433B,this LSI is provided with a synchronous mode in which it operates by the 384fs system synchoronous clock and an asynchronous mode in which it operates by the system clock independent of the input serial clock 432fs or more so that it can be used in various applications.
      The YSF210B(OSF22) has 11 features.The first one is 8-times oversampling in two channels (exclusively for 2DAC).The second one is input selectable from 16/18/20/22 bits and output from 18/20/22 bits.The third one is noise shaping available at 18/20 bits output.The fourth one is linear phase FIR type filters (225-order,41-order and 21-order ones) connected in three vertical stages.The fifth one is 22-bit floating point multiplication and addition by the 23*22-bit multiplier(with a built-in overflow limiter).The sixth one is filter characteristics,stop band attenuation is -100dB or more (0.5465fs to 7.4535fs),pass band ripple is within +-0.0005dB(0 to 0.4535fs).The seventh one is for the system clock,384fs in synchronous mode or over 432fs in asynchronous mode selectable.The eighth one is the input bit clock rates is 32fs,48fs,64fs,80fs,96fs,112fs,128fs,144fs,160fs,176fs and 192fs.The ninth one is sampling frequencies is 32KHz,44.1KHz, and 48KHz.The tenth one is 5V power supply,si-gate CMOS process.The eventh one is 24-pin SOP.
      The YSF210B(OSF22) has some information about absolute maximum rating.When parameter is power supply voltage,the symbol is VDD,the rating is -0.3 to 7.0,the unit is V.When parameter is input voltage,the symbol is VI,the rating is -0.3 to VDD+0.5,the unit is V.When parameter is operating temperature,the symbol is Top,the rating is -10 to 75,the unit is .When parameter is storage temperature,the symbol is Tstg,the rating is -50 to 125,the unit is .
