POWER ON
The PCM1808 has an internal power-on-reset circuit, and initialization (reset) is performed automatically when
the power supply (V
) exceeds 2.2 V (typical). While V
< 2.2 V (typical), and for 1024 system-clock counts
after V
DD
> 2.2 V (typical), the PCM1808 stays in the reset state and the digital output is forced to zero. The
digital output is valid after the reset state is released and the time of 8960/f
S
has elapsed. Because the fade-in
operation is performed, it takes additional time of 48/f
or 48/f
until the data corresponding to the analog input
signal is obtained.
Figure 19
illustrates the power-on timing and the digital output.
