4.6.2.2 Serial Audio Input Modes
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
Figure
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
