1.6.2 Digital Audio Input Timing

1.6.2.1 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 Figure 20 for timing.
