Reset
PCM1718 has both internal power on reset circuit and the
RSTB-pin (pin 15) which accepts external forced reset by
RSTB = LOW. For internal power on reset, initialize (reset)
is done automatically at power on V
DD
>2.2V (typ). During
internal reset = LOW, the output of the DAC is invalid and
the analog outputs are forced to V
CC
/2. Figure 6 illustrates
the timing of internal power on reset.
For the RSTB-pin, PSTB-pin accepts external forced reset by
RSTB = L. During RSTB = L, the output of the DAC is
invalid and the analog outputs are forced to V
CC
/2 after
internal initialize (1024 system clocks count after RSTB = H.)
Figure 7 illustrates the timing of RSTB-pin reset.
