Audio Out Interface Signals

No.
Type
Description
AO_OSCLK
B14
O
Over-Sampling Clock
. This output can be programmed to emit any fre-
quency up to 40 MHz, with a sub-Hertz resolution. It is intended for use
as the 256 or 384 f
s
over-sampling clock by the external D/A conversion
subsystem. A board-level 27 to 33
series resistor is recommended to
reduce ringing.
AO_SCK
A14
I/O
Serial Clock
. When the Audio Out (AO) module is programmed to act as
the serial interface timing slave (power-up default), AO_SCK acts as an
input. It receives the Serial Clock from the external audio D/A sub-
system. The clock is treated as fully asynchronous to the
CS1301/CS1311 main clock.
When the AO module is programmed to act as the serial interface timing
master, AO_SCK acts as an output. It drives the serial clock for the
external audio D/A subsystem. The clock frequency is a programmable
integral divisor of the AO_OSCLK frequency. AO_SCK is limited to 22
MHz. The sample rate of valid samples embedded within the serial
stream is variable. If used as an output, a board-level 27 to 33
series
resistor is recommended to reduce ringing.
AO_SD1
B13
O
Serial Data Buses
. Serial data to external stereo audio D/A subsystem.
The timing of transitions on this output is determined by the
CLOCK_EDGE bit in the AO_SERIAL register, and can be on positive or
negative AO_SCK edges.
AO_SD2
A13
AO_SD3
C12
AO_SD4
B12
AO_WS
A15
I/O
Word-Select or Frame synchronization
. Signal from/to the external
D/A subsystem. Each audio channel receives 1 sample for every WS
period.
When the AO module is programmed as the serial interface timing slave
(power-up default), AO_WS acts as an input. AO_WS is sampled on the
opposite AO_SCK edge from which AO_SDx are asserted.
When the AO module is programmed as serial interface timing master,
AO_WS acts as an output. AO_WS is asserted on the same AO_SCK
edge as AO_SDx.
Note:
The AO module always acts as sender, but can be master or slave for D/A timing.

S/PDIF Interface Signals
Signal Name
Ball
No.
Type
Description
SPDO
A12
O
S/PDIF Data Out.
Self-clocking serial data stream as per IEC958, with
1937 extensions. Note that the low impedance output buffer requires a
27 to 33
series terminator close to CS1301/CS1311 in order to match
the board trace impedance. This series terminator must be part of the
voltage divider needed to create the coaxial output through the AC isola-
tion transformer.
