YM3414

The YM3414 (ACDDF) is a kind of 2-channel 8-times oversampling digital filter.There are some features of YM3414 as follows.First is 8-times oversampling in two channels.The second is 19 * 18 bits multiplier built in.Then is floating point multiplier and accumlator having a coefficient of 18 bits.Next is overflow limiter built in.The fifth is high precision oscillator specially designed for use with the filter.The sixth is CMOS type processor.The seventh is single 5 V power supply.The last one is 16-pin type DIP package.

What comes next is about the absolute maximum ratings of YM3414.The VDD (power supply voltage) is from -0.3 V to +7.0 V.The VI (input voltage) is from -0.3 to Vdd+0.5 V.The Top (operating ambient temperature) is from -20 to +75.The Tstg (storage temperature) is from -50 to +125.Then is about the recommended operating conditions.The minimum VDD (power supply voltage) is 4.75 V,the typicall is 5.0 V and the maximum is 5.25 V.The minimum Top (operating temperature) is 0 and the maximum is 70.The minimum XIN (clock frequency) is 12.2 MHz, the typical is 16.93 MHz and the maximum is 18.5 MHz.

The following is about the DC characteristics (Ta=25,VDD=5±0.25 V) of YM3414.The standard power dissipation is 200 mW and the maximum is 270 mW at Vdd=+5 V.The minimum VOH (output high voltage) is 2.4 V and the maximum is Vdd V.The minimum VOL (output low voltage) is 0 V and the maximum is 0.4 V.The minimum output delay (delay from BCO) is 5 ns and the maximum is 35 ns.The minimum input data setup time (rise of BCI) is 50 ns.The minimum input data hold time (rise of BCI) is 20 ns.The standard XI ON/OFF time (duty) is 50%.The standard BCI ON/OFF time (duty) is 50%.
