Clock Control
The digital signal paths in the IC require a master clock
(MCLK) between 10MHz and 60MHz to function. The
MAX98089 requires an internal 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 MAX98089 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, four 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 per-
formance. 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.
U
DAC Low-Power Mode: This mode bypasses the
PLL for reduce power consumptions and uses fixed
counters to generate the clocks. The DAI__DAC_LP
bits override the other clock settings.
