timing requirements (continued)
power-on reset functions
The PCM1606 includes a power-on reset function. Figure 2 shows the operation of this function. With the
system clock active and VCC > 3 V typical (2.2 V to 3.7 V), the power-on reset function is enabled. The
initialization sequence requires 1024 system clocks from the time VCC > 3 V. After the initialization period, the
PCM1606 is set to its reset default state.
