The MAX5556 transitions from external serial clock
mode to internal serial clock mode if no SCLK signal is
detected for one LRCLK period. In internal clock mode,
SCLK is derived from and is synchronous with MCLK

nized with MCLK). Figure 6 details the internal serial
clock mode timing parameters. Figure 7 details the
