5.7 Switching Characteristics: TDM, I2S or LJ Interface

at TA = 25°C, IOVDD = 3.3V or 1.8V and 20pF load on all outputs (unless otherwise noted); see Figure 5-1 for timing diagram where DOUT refers to Daisy Chain Output when applicable
PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
td(DOUT-BCLK) BCLK to DOUT delay 50% of BCLK to 50% of DOUT, IOVDD = 1.8V 26 ns
50% of BCLK to 50% of DOUT, IOVDD = 3.3V 19
td(DOUT-FSYNC) FSYNC to DOUT delay in TDM mode 50% of FSYNC to 50% of DOUT, IOVDD = 1.8V 26 ns
FSYNC to DOUT delay in TDM mode 50% of FSYNC to 50% of DOUT, IOVDD = 3.3V 19
f(BCLK) BCLK output clock frequency; controller mode(1) IOVDD = 1.8V 12.288 MHz
IOVDD = 3.3V 24.576
td(FSYNC) BCLK to FSYNC delay; controller mode 50% of BCLK to 50% of FSYNC, IOVDD = 1.8V 26 ns
50% of BCLK to 50% of FSYNC, IOVDD = 3.3V 19
tH(BCLK) BCLK high pulse duration; controller mode IOVDD = 1.8V 36 ns
IOVDD = 3.3V 18
tL(BCLK) BCLK low pulse duration; controller mode IOVDD = 1.8V 36 ns
IOVDD = 3.3V 18
tr(BCLK) BCLK rise time; controller mode 10% - 90% rise time, IOVDD = 1.8V 10 ns
10% - 90% rise time, IOVDD = 3.3V 10
tf(BCLK) BCLK fall time; controller mode 90% - 10% fall time, IOVDD  = 1.8V 10 ns
90% - 10% fall time, IOVDD  = 3.3V 10
(1) To meet the timing specifications, the BCLK output clock frequency must be lower than 18.5MHz, if the DOUT data line is latched on the opposite BCLK edge polarity from the one used by the device to transmit DOUT data at IOVDD = 3.3V.
