In this document, the generic PNX1300 name refers
to the PNX1300 Series, or the PNX1300/01/02/11
products.
The PNX1300 Audio Out (AO) unit contains many fea-
tures not available in the TM-1000 and the TM-1100. It
has up to 8 channels, and drives up to 4 external stereo
D/A converters through a flexible bit-serial connection.
It provides all signals to interface to high quality, low cost
oversampling D/A converters, including a precisely pro-
grammable oversampling D/A system clock. The AO unit
and external D/A’s together provide the following capa-
bilities:
• Up to 8 channels of audio output.
• 16-bit or 32-bit samples per channel.
• Programmable sampling rate.
• Internal or external sampling clock source.
• Autonomously reads processed audio data from
memory using double buffering (DMA).
AUDIO OUT OVERVIEW
• Supports 16-bit mono and stereo PC standard mem-
• Supports little- and big-endian memory formats.
• Provides control capability for highly integrated PC
• No support for connecting several D/As to one serial

Seven PNX1300 pins are associated with the AO unit.
The AO_OSCLK output is an accurately programmable
clock output intended to be used as the master system
clock for the external D/A subsystem. The other pins
(AO_SCK, AO_WS and AO_SDx) constitute a flexible
serial output interface. Using the AO MMIO registers,
these pins can be configured to operate in a variety of se-
rial interface framing modes, including but not limited to:
• Standard stereo I
