SYSTEM CLOCK
The PCM1850/1851 supports 256 f
S
, 384 f
S
, 512 f
S,
and 768 f
S
as the system clock, where f
S
is the audio sampling
frequency. The system clock must be supplied on SCKI (pin 7).
The PCM1850/1851 has a system clock detection circuit which automatically senses if the system clock is operating at
256 f
S
, 384 f
S
, 512 f
S
or 768 f
S
in slave mode. In master mode, the system clock frequency must be selected by mode control
via the serial port. The 768-f
S
system clock is not available in master mode or for f
S
= 88.2 kHz and 96 kHz in the slave
mode. The system clock is divided into 128 f
S
and 64 f
S
automatically, and these frequencies are used to operate the digital
filter and the delta-sigma modulator, respectively.
Table 1 shows the relationship of typical sampling frequency to system clock frequency, and Figure 20 shows system clock
timing.
