Note:
1.
w
Test Conditions
DCVDD = 1.42V, DBVDD = AVDD = HPVDD = SPKRVDD = PLLVDD = 3.3V, DGND = AGND = PLLGND = 0V, T
Slave Mode, fs = 48kHz, MCLK = 256fs, 24-bit data, unless otherwise stated.
PARAMETER
Audio Data Input Timing Information
BCLK / VXCLK cycle time
BCLK / VXCLK pulse width high
BCLK / VXCLK pulse width low
LRC / VXFS set-up time to BCLK / VXCLK rising edge
LRC / VXFS hold time from BCLK / VXCLK rising edge
DACDAT / VXDIN hold time from BCLK / VXCLK rising
edge
ADCDAT / VXDOUT propagation delay from BCLK /
VXCLK falling edge
BCLK / VXCLK period should always be greater than or equal to MCLK / VXCLK period.
