4.6.2 Digital Audio Input Timing
4.6.2.1 AES/EBU Format Input
A 6.144MHz (128fs) audio clock must be supplied to the ACLKA and ACLKB inputs.
ACLKA is used to clock the AES/EBU digital audio signal for channels 1 to 4 (AIN1/2 and
AIN3/4) into the device. ACLKB is used to clock the AES/EBU digital audio signal for
channels 5 to 8 (AIN5/6 and AIN7/8) into the device. In AES/EBU input mode, the
WCINB and WCINB external pins should be grounded. See
