Power-On Reset Functions
The PCM1753/54/55 includes a power-on reset function. Figure 20 shows the operation of this function. With
the system clock active and V
CC
> 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 V
CC
> 3 V (typical, 2.2 V to 3.7 V). After the
initialization period, the PCM1753/55 is set to its reset default state, as described in the
Mode Control Registers
section of this data sheet.
During the reset period (1024 system clocks), the analog output is forced to the bipolar zero level, or V
CC
/2.
After the reset period, an internal register is initialized in the next 1/f
S
period and if SCK, BCK, and LRCK are
provided continuously, the PCM1753/54/55 provides proper analog output with unit group delay against the
input data.
