Equation 2: PCM_CLK Frequency When Being Generated Using the Internal 48MHz Clock
The frequency of PCM_SYNC relative to PCM_CLK can be set using Equation XXX:
Equation 3: PCM_SYNC Frequency Relative to PCM_CLK
CNT_RATE, CNT_LIMIT and SYNC_LIMIT are set using PSKEY_PCM_LOW_JITTER_CONFIG. As an
example,
to
generate
PCM_CLK
at
512kHz
with
PCM_SYNC
at
8kHz,
set
PSKEY_PCM_LOW_JITTER_CONFIG to 0x08080177.
9.9 PCM Configuration
The PCM configuration is set using two PS Keys, PSKEY_PCM_CONFIG32 detailed in Table 12 and
PSKEY_PCM_LOW_JITTER_CONFIG in Table 13. The default for PSKEY_PCM_CONFIG32 is 0x00800000,
i.e., first slot following sync is active, 13-bit linear voice format, long frame sync and interface master
generating 256kHz PCM_CLK from 4MHz internal clock with no tri-state of PCM_OUT.
