4.6.2 Digital Audio Input Timing
4.6.2.1 AES/EBU Format Input
AIN1/2, AIN3/4
AIN5/6, AIN7/8
ACLKA/B
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
