PCM1851A

SLES173 – MARCH 2006

The PCM1850A/1851A has an internal power-on-reset circuit, and initialization (reset) is performed automatically

at the time that the power supply (VDD) exceeds 2.2 V (typical). While VDD < 2.2 V (typical) and for 1024 system

clocks after VDD > 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/fS 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.
