4.6.2.2 Serial Audio Input Modes
AIN1/2, AIN3/4
AIN5/6, AIN7/8
ACLKA/B
WCINA/B
A 6.144MHz (128fs) audio clock must be supplied to the ACLKA and ACLKB
inputs. The GS1503B divides this clock by 2 to clock the 3.072MHz audio data. An
audio word clock at 48kHz (fs) must also be supplied to the WCINA and WCINB
inputs, as shown in
registers 058h to 06Eh can be used to enter the 23 8-bit bytes of the Audio Channel
Status Block, as defined in AES3-1992. NOTE: The CRC byte is generated
internally by the GS1503B. The GS1503B will default to Professional audio mode
with 24-bit word length and emphasis off. See
