2.5.7
The Audio In (AI) and Audio Out (AO) units are similar to
the video units. They connect to most serial ADC and
DAC chips, and are programmable enough to handle
most serial bit protocols. These units can transfer MSB
or LSB first and left or right channel first.
The audio sampling clock is driven by PNX1300 and is
software programmable within a wide range. Like the VO
unit, AI and AO sample rates are separately and dynam-
ically programmable. The high-quality on-chip sample
clock generator circuits allows the programmer subtle
control over the sampling frequency so that audio and
video synchronization can be achieved in any system
configuration. When changing the sample frequency, the
instantaneous phase does not change, which allows
sample frequency manipulation without introducing au-
dio or video distortion.
As with the video units, the audio-in and audio-out units
buffer incoming and outgoing audio data in SDRAM. The
audio-in unit buffers samples in either 8- or 16-bit format,
mono or stereo. The audio-out unit transfers 16- or 32-bit
sample data for mono, stereo or up to 8 audio channels
from memory to the external DACs. Any manipulation or
mixing of sound data is performed by the DSPCPU since
this processing will require only a small fraction of its pro-
cessing capacity.
2.5.8
The Sony/Philips Digital Interface Out (SPDO) unit al-
lows output of a 1-bit high-speed serial data stream. The
primary application is output of digital audio data in Sony/
Philips Digital Interface (S/PDIF) format to an external
electrically isolated transformer. The SPDO unit can also
be used as a general purpose high-speed data stream
output device such as a UART.
The SPDO unit supports 2-channel PCM audio, one or
more Dolby Digital six-channel data streams, or one or
more MPEG-1 or MPEG-2 audio streams (embedded
per Project 1937). It supports arbitrary programmable
sample rates independent of and asynchronous to the
AO unit sample rate.
2.5.9
The on-chip synchronous serial interface (SSI) is spe-
cially designed to interface to high integration analog mo-
dem frontends or ISDN frontend devices. In the analog
modem case, all of the modem signal processing is per-
formed in the PNX1300 DSPCPU.
