Multi-Channel Isochronous Streaming FireWire Audio Controller  
Oxford Semiconductor, Inc.  
Overview  
The Oxford Semiconductor OXFW971 is a highly-integrated audio  
®
streaming controller for FireWire isochronous applications. The  
OXFW971 builds on the achievements of the OXFW970, but offers a  
range of additional features:  
„
Up to 16 I/O channels with multiple configuration options,  
including:  
†
Simultaneous 8 input & 8 output (up to 96 kHz sample  
rate)  
†
†
S/PDIF input & S/PDIF output (up to 96 kHz sample rate)  
MIDI input & MIDI output  
„
„
High peripheral integration, resulting in lower operational  
production costs  
Improved processor performance, to support an equalization  
function for certain applications  
The OXFW971 provides a bidirectional FireWire S400/S800 link between  
®
a PC or Mac and a range of audio interfaces. The combination of eight  
audio channels (both input & output) with support for both  
S/PDIF and musical instrument digital interface (MIDI) make the  
™
OXFW971 a highly-integrated solution for GarageBand I/O boxes,  
®
external sound card and speaker applications. With an ARM7TDMI  
embedded processor, 1 Mbits of flash memory and a range of peripherals  
integrated on-chip, the device provides a low-cost solution for a variety  
of applications.  
Device  
The OXFW971 has a sophisticated clocking scheme, which allows it to be  
used in a variety of system configurations. It supports an external word  
clock input and can generate a low-jitter audio master clock (128, 192,  
256, 384 or 512 fs) for external DACs, with optional clock smoothing.  
Functionality  
The high-speed UART allows applications with a second microcontroller  
to be controlled through the FireWire link. This facility allows users to  
interface with their preferred microprocessors, utilizing a transparent  
channel over a 1394 link. Such a feature can be useful where it is  
necessary to re-use existing firmware or support more specific customer  
applications. Other devices, such as DACs, can be controlled by the low-  
speed serial interfaces, which are compatible with two-wire serial and  
SPI interfaces.

Multi-Channel Isochronous Streaming FireWire Audio Controller  
Applications  
The OXFW971 connects seamlessly to a range of audio processor chips  
®
for applications that require AC-3/DTS decoding, Dolby Virtual audio  
processing or Virtual Pro Logic II surround sound, including the  
following:  
„
„
Prosumer breakout boxes  
External surround sound cards for laptops—for DVD playback,  
games & music  
„
„
Sound card solutions requiring multiple I/O S/PDIF output  
Musical I/O interfaces with 8-in/8-out channels; MIDI in/out,  
S/PDIF in/out  
„
„
Speaker solutions with streamed 7.1/5.1/2.1/2.0 output  
Bus-powered 2.0/2.1 FireWire speakers  
Figure 1 shows how the OXFW971 might be used in a prosumer  
breakout box; in this example, using 8 in/out, S/PDIF in/out and MIDI in/  
out.

The Audio1 and Audio2 NFS clock output pins are not necessarily associated with the Audio1 and  
Audio2 cores; they are selectable. Before committing to an application design, check which clock is  
associated with which core. See the Clocks chapter in the OXFW971 Hardware Reference Manual for  
details.  
The function of the Audio1 and Audio2 bit clocks differs according to whether the OXFW971 is used in  
slave or master mode. For details, see the Clocks chapter in the OXFW971 Hardware Reference Manual.  
As shown in Table 5, any of the 32 GPIO pins can be assigned to a  
primary function, an alternative function or as general-purpose I/O in  
response to the peripheral control register settings. See the OXFW971  
Hardware Reference Manual for further details.

GPIO11 is the JTAG/UART selection pin, which is input only.  
When JTAG_UART_SEL=0, UART1 signals are routed to the JTAG pins, irrespective of function  
settings on these pins; when JTAG_UART_SEL=1, JTAG signals are routed to the JTAG pins.  
To use UART1 on these pins, JTAG_UART_SEL must be tied high.  
Default.

The following rules apply to pin function selection:  
„
Input signals on a pin are routed to all functions of that pin,  
irrespective of which function is selected  
„
Pins do not necessarily default to their primary function
