Both the PCM3002 and PCM3003 have internal power-on reset circuitry. Power-on reset occurs when the
system clock (SYSCLK) is active and V
DD
> 2.2 V. For the PCM3003, the SYSCLK must complete a minimum of
three complete cycles prior to V
DD
> 2.2 V to ensure proper reset operation. The initialization sequence requires
1024 SYSCLK cycles for completion, as shown in Figure 45. Figure 46 shows the state of the DAC and ADC
outputs during and after the reset sequence.
