POWER-ON-RESET SEQUENCE
The PCM1850A/1851A has an internal power-on-reset circuit, and initialization (reset) is performed automatically
at the time that the power supply (V
DD
) exceeds 2.2 V (typical). While V
DD
< 2.2 V (typical) and for 1024 system
clocks after V
DD
> 2.2 V (typical), the PCM1850A/1851A 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 4500/f
has passed. At the
moment of the power-on-reset release, the PCM1850A/1851A does not need a system clock.
Figure 21
illustrates the internal power-on-reset timing and the digital output for power-on reset.
