YM3433

The YM3433 is a kind of 2 channel 8 times oversampling digital filter which operates via serial input signal and independent system clock.There are some features of YM3433 as follows.First, because this operates with a serial input signal and an independent system clock, this can handle all of the input bit clock rates which follow with no supplementary circuit: input signals-32 fs, 48 fs, 64 fs, 80 fs, 96 fs, 112 fs, 128 fs, 144 fs, 160 fs, 176 fs, 192 fs.The second is built-in overflow limiter.Then is 16 bit/18 bit output switching (compatible with PCM56/PCM58).Next is 1DAC (4-times)/2DAC (8-times) switching.The last one is CMOS process, +5 V pin plastic DIP.

What comes next is about the absolute maximum ratings of YM3433.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 and the maximum is 20.0 MHz.

The following is about the DC characteristics (Ta=25,VDD=5±0.25 V) of YM3433.The maximum power dissipation is 300 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 DLO,DRO setup time is 15 ns.The minimum DLO,DRO time is 15 ns.The standard XI ON/OFF time (duty) is 50%.The standard BCI ON/OFF time (duty) is 50%.
