UNIT

Audio Interface Timing - Slave Mode

BCLK cycle time

tBCY

BCLK pulse width high

tBCH

BCLK pulse width low

tBCL

LRCLK set-up time to BCLK rising edge

tLRSU

LRCLK hold time from BCLK rising edge

tLRH

DACDAT hold time from BCLK rising edge

tDH

ADCDAT propagation delay from BCLK falling edge

tDD

DACDAT set-up time to BCLK rising edge

tDS

Note: BCLK period must always be greater than or equal to MCLK period.

Note: the descriptions above assume non-inverted polarity of BCLK and LRCLK.
