6.11 Switching Characteristics: TDM, I2S or LJ Interface

at TA = 25°C, IOVDD = 3.3 V or 1.8 V and 20-pF load on all outputs (unless otherwise noted); see TBD for timing diagram
PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
td(SDOUT-BCLK) BCLK to SDOUT delay 50% of BCLK to 50% of SDOUT, IOVDD = 1.8 V 18 ns
50% of BCLK to 50% of SDOUT, IOVDD = 3.3 V 14
td(SDOUT-FSYNC) FSYNC to SDOUT delay in TDM or LJ mode (for MSB data with TX_OFFSET = 0) 50% of FSYNC to 50% of SDOUT, IOVDD = 1.8 V 18 ns
50% of FSYNC to 50% of SDOUT, IOVDD = 3.3 V 14
f(BCLK) BCLK output clock frequency; master mode (1) 24.576 MHz
tH(BCLK) BCLK high pulse duration; master mode IOVDD = 1.8 V 14 ns
IOVDD = 3.3 V 14
tL(BCLK) BCLK low pulse duration; master mode IOVDD = 1.8 V 14 ns
IOVDD = 3.3 V 14
td(FSYNC) BCLK to FSYNC delay; master mode 50% of BCLK to 50% of FSYNC, IOVDD = 1.8 V 18 ns
50% of BCLK to 50% of FSYNC, IOVDD = 3.3 V 14
tr(BCLK) BCLK rise time; master mode 10% - 90% rise time, IOVDD = 1.8 V 10 ns
10% - 90% rise time, IOVDD = 3.3 V 10
tf(BCLK) BCLK fall time; master mode 90% - 10% fall time, IOVDD = 1.8 V 8 ns
90% - 10% fall time, IOVDD = 3.3 V 8
(1) The BCLK output clock frequency must be lower than 18.5 MHz (to meet the timing specifications), if the SDOUT data line is latched on the opposite BCLK edge polarity than the edge used by the device to transmit SDOUT data.
