Table 11. Clock Control Registers
Clock Control
The digital signal paths in the IC require a master
clock (MCLK) between 10MHz and 60MHz to func-
tion. Internally, the MAX9888 requires a clock between
10MHz and 20MHz. A prescaler divides MCLK by 1, 2,
or 4 to create the internal clock (PCLK). PCLK is used to
clock all portions of the IC.
The MAX9888 includes two digital audio signal paths,
both capable of supporting any sample rate from 8kHz
to 96kHz. Each path is independently configured to allow
different sample rates. To accommodate a wide range
of system architectures, three main clocking modes are
supported:
U
PLL Mode: When operating in slave mode, enable
the PLL to lock onto any LRCLK input. This mode
requires the least configuration, but provides the
lowest performance. Use this mode to simplify initial
setup or when normal mode and exact integer mode
cannot be used.
U
Normal Mode: This mode uses a 15-bit clock divider
to set the sample rate relative to PCLK. This allows
high flexibility in both the PCLK and LRCLK frequen-
cies and can be used in either master or slave mode.
U
Exact Integer Mode (DAI1 only): In both master and
slave modes, common MCLK frequencies (12MHz,
13MHz, 16MHz, and 19.2MHz) can be programmed
to operate in exact integer mode for both 8kHz and
16kHz sample rates. In these modes, the MCLK and
LRCLK rates are selected by using the FREQ1 bits
instead of the NI, and PLL control bits.
