to configure jumpers and switches on both the Audio EZ-Extender
and EZ-KIT Lite boards. For custom setups use “System Architecture” on page 2-2 in conjunction with “Configuration Jumpers and
Switches” on page 2-4.
Analog Audio Interface
For analog audio applications, the Audio EZ-Extender uses two AD1938
multichannel 192 kHz audio codecs. The AD1938 is a high-performance,
single-chip codec chip that provides four analog-to-digital converters
(ADCs) with differential inputs and eight digital-to-analog converters
(DACs) with single-ended outputs. The DAC outputs operate using
ADI’s patented multibit sigma-delta architecture. The chip provides auxiliary input and output SPORTs for connecting to other codecs, increasing
the number of channels a single SPORT uses. A serial peripheral interface
(SPI) port is included, allowing the microcontroller to adjust volume and
many other audio parameters.
For a picture of the audio interface connections, see Figure 2-1 on
page 2-3. For more detailed information, see “Schematics on page B-1”.
The two AD1938 chips (referred to as AD1938_A and AD1938_B in the
block diagrams) connect in parallel to a single SPORT. The chips connect
for a time-division multiplexed (TDM) output mode:
• At a 48 kHz sample rate, TDM mode allows up to 16 channels of
data to be sent from each chip in each direction. Each chip uses
four of the 16 input channels and eight of the 16 output channels.
1-2
Blackfin Audio EZ-Extender Manual
Audio EZ-Extender Interfaces
The number of channels can be set up in the control registers and
is dependant on the sample rate. As the sample rate increases, the
number of possible channels decreases.
• At 96 kHz, the AD1938 operates with a maximum of eight channels in each direction. At 96 kHz, all of the TDM channels are
used by all analog outputs, but there are still four extra input channels, two of which can be used by the digital inputs.
• At the 192 kHz sample rate, a maximum of four channels in each
direction can be used, meaning that four of the output channels
cannot be used.
The auxiliary SPORTs of the AD1938_A codec connect to the
ADAV801’s auxiliary SPORT (see “System Architecture” on page 2-2 for
more information). The Sony Philips Digital Interface (SPDIF) stream
requires two channels of the TDM stream for each direction: two channels
for left and right input audio, and two channels for left and right output
audio.
If the AD1938 runs at the 48 kHz sample rate, both the input and output
digital streams can be put into the TDM stream. In this case, all of the
clocks in the system must be set up relative to the recovered clock from the
SPDIF input.
At the 96 kHz sample rate, only the SPDIF inputs is able to be added to
the TDM stream. This is because at 96 kHz, only eight outputs channels
are available and they are all being used by the outputs.
The internal phase-locked loop (PLL) of the AD1938 codec can be configured to generate all of the clocking and frame sync signals. The source
clock of the PLL can be from either the serial port frame sync or an externally supplied clock. The external master clock (MCLK) comes from the
ADAV801 codec. A jumper (JP2) allows the master clock to come directly
from the SYSCLK3 pin of the ADAV801 or from a divided version of the
SYSCLK1, either divided by 2 or 4. The divided clocks are necessary when a
Blackfin Audio EZ-Extender Manual

Digital Audio Interface
sample rate less than 32 kHz is required. Otherwise, a signal clock frequency at the MCLK pin of the AD1938 can generate the 48 kHz, 96 kHz,
or 192 kHz sample rate.
The analog input pins of the AD1938’s input signals operate in the range
from 0 Vrms to 1 Vrms. To allow larger signals to be input at the RCA
jacks, the input amplifiers (external to the AD1938) are capable of attenuating the signals. See “Configuration Jumpers and Switches” on page 2-4
for more information.
The analog output pins of the AD1938’s output signals operate in the
range from 0 Vrms to 1 Vrms. The output amplifiers are set to a gain of
1.5x, giving the system unity gain when switches SW1–4 are all ON.
Example programs demonstrating the capabilities of the audio interface
are included in the in the
\…\Blackfin\EZ-KITs\Audio EZ-EXTENDER\Examples subdirectory of the
VisualDSP++ installation directory.
For more information about the AD1938 codecs, go to http://www.analog.com and search for AD1938.
Digital Audio Interface
For digital audio applications, the Audio EZ-Extender uses the ADAV801
codec chip. The ADAV801 chip has an analog stereo input, analog stereo
output, digital stereo input, and a digital stereo output. In addition to
these inputs and outputs, the ADAV801 also has an internal sample rate
converter, which can be used to change the sample rate between the different interfaces. On the Audio EZ-Extender, the analog input and outputs
are not used. The digital interface can operate at up to a 200 kHz sample
rate. The ADAV801 operates in the I2S mode, which allows only two
channels (left and right) of input and two channels of output. It also has
an auxiliary serial port for connecting to other devices. The configuration
registers are configured using an SPI port connected to the processor.
1-4
Blackfin Audio EZ-Extender Manual
Audio EZ-Extender Interfaces
The ADAV801 has two internal PLLs, which can produce all of the necessary internal clocks for the different interfaces of the chip. An external
27 MHz oscillator is used as a clock source for the PLLs. The external
clocks, which also go to the AD1938 codecs, are generated from the PLLs.
The recovered clock from the SPDIF input can be used as a clock input
for the serial ports, as well as for the generated external clock output
SYSCLK3.
The primary serial port of the ADAV801 codec connects to the processor
on the mother board, while the secondary serial port connects to the
AD1938_A codec. For a picture of the digital audio interface connections,
see “System Architecture” on page 2-3. For more detailed information, see
“Schematics on page B-1”. The internal routing of the different interfaces
of the ADAV801 is completely configurable. The SPDIF input and output can be separately routed to either or both the primary and secondary
serial ports.
Example programs demonstrating the capabilities of the digital audio
interface are included in the in the
\…\Blackfin\EZ-KITs\Audio EZ-EXTENDER\Examples subdirectory of the
VisualDSP++ installation directory.

System Architecture
System Architecture
A picture of the board layout, connector and jumper locations is shown in
Figure 2-2 on page 2-5. A block diagram of the Audio EZ-Extender is
shown in Figure 2-1.
The analog audio interface consists of two AD1938 audio codecs (referred
to as AD1938_A and AD1938_B codecs), which use one of the processor’s serial ports (SPORTs). All of the clock and frame sync signals must
be driven by one of the AD1938 chips. The analog audio interface is configured for the time-division multiplexed (TDM) serial mode. In the
TDM mode, a single clock and frame sync are used to transmit and
receive the data. The data signals of the AD1938_A codec connect to the
processor’s primary SPORT TX and RX pins, and the data signals of the
AD1938_B codec connect to the secondary SPORT TX and RX pins (see
“Analog Audio Interface” on page 1-2).
The digital audio interface consists of the ADAV801 codec. The codec
chip communicates in the I2S mode. In the I2S mode, the transmit and
receive clock, along with the frame sync signals, are set individually to
transmit sample rate that is different from the receive sample rate.
The ADAV801 codec has a secondary transmit and receive SPORT,
which is interfaced with the auxiliary SPORT of the AD1938_A codec.
The interface operates in the I2S mode and is mastered by the ADAV801
chip. The interface allows the digital audio data steams to be multiplexed
into the analog audio data stream, facilitating access to all of the data signals via a single SPORT. This is dependent on the sample rate, as
described in “Analog Audio Interface” on page 1-2.
A jumper setting allows the routing of the processor’s SPORTs to be
swapped with the SPORTs of the analog and digital interfaces. If the
SPORT on the mother board is already in use, this feature allows either of

the audio interfaces to be used instead. In addition, each SPORT individually can be disabled and not driven by the Audio EZ-Extender on the
mother board. For more information, see the following sections:
• “SPORT Select Jumper (JP1.7/8)” on page 2-6
• “EZ-KIT Lite SPORT1 Enable Jumper (JP1.5/6)” on page 2-6
• “EZ-KIT Lite SPORT0 Enable Jumper (JP1.3/4)” on page 2-6.
Each of the Audio EZ-Extender’s ICs (AD1938_A, AD1938_B, and
ADAV801) is configured using the SPI interface of the processor. Each
chip includes its own chip select pin. On the ADSP-BF537 EZ-KIT Lite,
the location of the chip select signals on the expansion interface is different from that location on the ADSP-BF533 and ADSP-BF561 EZ-KIT
Lites. A jumper is used to define for which EZ-KIT Lite to set up the SPI
select signals. For more information, see “ADSP-BF537 EZ-KIT Lite
Select Jumper (JP1.1/2)” on page 2-5.
All of the expansion interface signals are passed directly through the board
from the EZ-KIT Lite to another set of expansion interface connectors.
This allows other EZ-Extender boards to be attached to the Audio
EZ-Extender.
Configuration Jumpers and Switches
Before using the Blackfin Audio EZ-Extender, follow the steps in “Audio
EZ-Extender Setup” on page 1-1.
Figure 2-2 shows the locations of all of the jumper headers. The jumper
headers are divided to show the placement and rotation of each jumper.
The jumpers are described by the pins of the header on which the jumpers
can be placed. For example, JP1.1/2 refers to a single jumper that can be
placed across pins 1 and 2 of JP1. The dark pin indicates pin 1 of each
header.

Configuration Jumpers and Switches
EZ-KIT Lite SPORT0 Enable Jumper (JP1.3/4)
Installing a jumper at this location enables the SPORT0 signals of the
EZ-KIT Lite to drive and be driven by the Audio EZ-Extender. Do not
install this jumper if SPORT0 is used elsewhere on the mother board.
EZ-KIT Lite SPORT1 Enable Jumper (JP1.5/6)
Installing a jumper at this location enables the SPORT1 signals of the
EZ-KIT Lite to drive and be driven by the Audio EZ-Extender. Do not
install this jumper if SPORT0 is used elsewhere on the mother board.
SPORT Select Jumper (JP1.7/8)
The JP1.7/8 jumper determines how SPORT0 and SPORT1 are routed to the
analog SPORT (SPORT_A) and the digital SPORT interface (SPORT_B). See
Figure 2-1 on page 2-3 for more details. The following table describes the
jumper connections.

AD1938 MCLK Source Jumper (JP2)
The JP2 jumper determines the source of the master clock (MCLK) of the
AD1938 audio codecs. The standard configuration connects the SYSCLK3
pin of the ADAV801 codec to MCLK by installing the JP2.5/6 jumper.
Two other jumper positions, JP2.1/2 and JP2.3/4, connect MCLK to the
ADAV801 codec’s SYSCLK1 pin divided by 4 and 2, respectively. These
positions can be used to supply the AD1938 codec with lower master
clock frequencies to reach the lower sample rates. For more information
2-6
Blackfin Audio EZ-Extender Manual
Audio EZ-Extender Hardware Reference
about the SYSCLK1 and SYSCLK3 pins, refer to the ADAV801 datasheet.
For more information on the MCLK frequencies and sample rates, see the
AD1938 datasheet.
SPDIF Loopback Jumper (JP4)
The JP4 jumpers are used for test purposes only; the SPDIF jumpers
loop-back the digital output signals to the digital input.
Analog Input Gain Switches (SW1–4)
The SW1–4 switches allow the gain of each analog input to be changed
from 1/(1.5) to 1/(2.12). This is useful when the input signals are too
large for the AD1938 codec to handle. The following table shows which
switch position corresponds to each analog input channel.
