PREFACE
Thank you for purchasing the ADSP-21375 EZ-KIT Lite®, Analog
Devices, Inc. evaluation system for SHARC® processors.
SHARC processors are based on a 32-bit super Harvard architecture that
includes a unique memory architecture comprised of two large on-chip,
dual-ported SRAM blocks coupled with a sophisticated I/O processor,
which gives a SHARC processor the bandwidth for sustained high-speed
computations. SHARC processors represents today’s de facto standard for
floating-point processing, targeted toward premium audio applications.
The evaluation system is designed to be used in conjunction with the
CrossCore® Embedded Studio (CCES) and VisualDSP++® development
environments to test capabilities of the ADSP-21375 SHARC processors.
The development environment aids advanced application code development and debug, such as:
• Create, compile, assemble, and link application programs written
in C++, C, and ADSP-21375 assembly
• Load, run, step, halt, and set breakpoints in application program
• Read and write data and program memory
• Read and write core and peripheral registers
• Plot memory

The ADSP-21375 EZ-KIT Lite board contains the National Instruments
Educational Laboratory Virtual Instrumentation Suite interface. The
interface features the DC voltage and current measurement modules,
oscilloscope and bode analyzer modules, function generator, arbitrary
waveform generator, and digital I/O.
The ELVIS interface is a LabVIEW-based design and prototype environment for university science and engineering laboratories. The ELVIS
ADSP-21375 EZ-KIT Lite Evaluation System Manual
1-13
Analog Audio
interface consists of LabVIEW-based virtual instruments, a multifunction
data acquisition (DAQ) device, and a custom-designed bench-top workstation and prototype board. This combination provides a ready-to-use
suite of instruments found in most educational laboratories. Because the
interface is based on LabVIEW and provides complete data acquisition
and prototyping capabilities, the system is ideal for academic coursework
that range from lower-division classes to advanced project-based
curriculums.
For more information on ELVIS and example demonstration programs,
visit National Instruments Web site at www.ni.com.
Analog Audio
The AD1835A device is a high-performance, single-chip codec featuring
four stereo digital-to-analog converters (DACs) for audio output and one
stereo analog-to-digital converters (ADCs) for audio input. The codec can
input and output data with a sample rate of up to 96 kHz on all channels.
A 192 kHz sample rate can be used with one of the DAC channels.
The processor is interfaced with the AD1835A codec via the DAI port.
The DAI pins can be configured to transfer serial data from the codec in
either time-division multiplexed (TDM) or 2-wire interface mode (TWI).
For more information about the codec’s connection to the DAI, see “DAI
Interface” on page 2-4.
The master input clock (MCLK) for the AD1835A codec can be generated
by the on-board 12.288 MHz oscillator or supplied by one of the DAI
pins of the processor. Using a DAI pin to generate the MCLK, as opposed to
the on-board oscillator, allows synchronization of multiple devices in the
system. It is possible to disable the on-board audio oscillator from driving
the audio codec and the processor’s input pin. For instructions on how to
configure the clock, refer to “Codec Setup Switch (SW3)” on page 2-11.
1-14
ADSP-21375 EZ-KIT Lite Evaluation System Manual
Using the ADSP-21375 EZ-KIT Lite
The AD1835A codec can be configured as a master or as a slave, depending on the DIP switch settings. In master mode, the codec drives the serial
port clock and frame sync signals to the processor. In slave mode, the processor must generate and drive all of the serial port clock and frame sync
signals. For more information, refer to “Codec Setup Switch (SW3)” on
page 2-11.
The internal configuration registers of the codec are configured using the
SPI port of the processor. The DPI pin 4 (DPI4 register) is used as the
select for the device. For information on how to configure the
multichannel codec, refer to the product data sheet at
AD1835A.
The RCA connector (J10) is used to input analog audio. When using an
electret microphone on this connector, configure switch SW4 according to
the instructions in “Electret Microphone Select Switch (SW4)” on
page 2-12. The four output channels are connected to the RCA
connector (J5). Channel 4 of the codec connects to the headphone
jack (J9). For more information, see “Connectors” on page 2-21.
Example programs are included in the EZ-KIT Lite installation directory
to demonstrate how to configure and use the on-board analog audio
interface.
LEDs and Push Buttons
The EZ-KIT Lite has eight general-purpose user LEDs and four general-purpose push buttons.
Two general-purpose push buttons are attached to the FLAG pins of the
processor, while the other two are attached to the DAI pins. All of the
push buttons are connected to the processor through a DIP switch (SW7).
The DIP switch can disconnect the processor pins connected to the push
buttons. See “Push Button Enable Switch (SW7)” on page 2-13 for

ADSP-21375 EZ-KIT Lite Evaluation System Manual
ADSP-21375 EZ-KIT Lite Hardware Reference
The CLKIN pin of the processor connects to a 16.384 MHz oscillator. The
core frequency of the processor is derived by multiplying the frequency at
the CLKIN pin by a value determined by the state of processor pins CLKCFG1
and CLKCFG0. The value at these pins is determined by the state of the SW2
switch (see “Boot Mode and Clock Ratio Select Switch (SW2)” on
page 2-10). By default, the EZ-KIT Lite provides a core frequency of
262.144 MHz. It is possible to change the speed of the processor by
changing the value of the PMCTL register.
The SW2 switch also configures the boot mode of the processor. The
EZ-KIT Lite is capable of EPROM/flash boot and SPI boot. By default,
the EZ-KIT Lite boots from flash memory. For details, see “Boot Mode
and Clock Ratio Select Switch (SW2)” on page 2-10.

schematics show unpopulated S/PDIF components which were
used when populating with the ADSP-21371 processor.
External Port
The external port of the ADSP-21375 processor consists of a 24-bit
address bus, 16-bit data memory bus, and control lines. The control lines
are used to select, read, and write to external memory devices.
The external port connects to an 8-bit parallel flash memory and a 16-bit
SDRAM memory. See “External Memory” on page 1-12 for more information about accessing flash and SDRAM memories.
All of the external port signals are available externally via the expansion
interface connectors (J1—3). The pinout of the connectors can be found in
“ADSP-21375 EZ-KIT Lite Schematic” on page B-1.

DAI Interface
The digital application interface (DAI) pins are connected to the signal
routing unit (SRU) of the processor. The SRU is a flexible routing system,
providing a large system of signal flows within the processor. In general,
the SRU can route the DAI pins to different internal peripherals in various combinations.
The DAI pins are connected to the AD1835A audio codec, a 26-pin
header, two RCA connectors, audio oscillator output, an external phase
lock loop (PLL) circuit, two LEDs, and two push buttons. Figure 2-2
illustrates the EZ-KIT Lite’s connections to the DAI interface.

ADSP-21375 EZ-KIT Lite Hardware Reference
To use the DAI for a different purpose, disable any signal driving a DAI
pin with a switch (see “Codec Setup Switch (SW3)” on page 2-11).
In addition, SW3 enables flexible routing of the 12.288 MHz audio oscillator’s output signal. By default, the signal is used as the master clock (MCLK)
for the AD1835A codec.
All of the DAI signals are available externally via the expansion interface
connectors (J1—3) and 0.1” spaced header (P4). The pinout of the connectors can be found in “ADSP-21375 EZ-KIT Lite Schematic” on page B-1.
DPI Interface
The digital peripheral interface (DPI) pins are connected to a second signal routing unit of the processor (SRU2). The SRU2 unit, similar to the SRU,
is a flexible routing system, providing a large system of signal flows within
the processor. In general, the SRU2 can route the DPI pins to different
internal peripherals in various combinations.
The DPI pins are connected to the SPI flash memory, SPI of the
AD1835A codec, a UART, a 20-pin header, and five LEDs. Figure 2-3
illustrates the EZ-KIT Lite’s connections to the DPI interface.
To use the DPI for a different purpose, disable any signal driving a DPI
pin with a switch (see “UART Enable Switch (SW5)” on page 2-12). Any
DPI pin connected to a LED can be used without having to disconnect
the pin. You can, however, see the respective LED turn ON and OFF when
the signal is used elsewhere on the board.
All of the DPI signals are available externally via the expansion interface
connectors (J1—3) and 0.1” spaced header (P3). The pinout of the connectors can be found in “ADSP-21375 EZ-KIT Lite Schematic” on page B-1.

External PLL
The ADSP-21375 EZ-KIT Lite contains an external phase lock loop to
help generate a faster and more stable master input clock, MCLK. The PLL
uses DAI pin 3 as an input clock from the ADSP-21375 processor. The
new clock generated by PLL connects to the processor via DAI pin 2.
Example programs are included in the EZ-KIT Lite installation directory
to demonstrate how to configure and use the board’s external PLL.
Expansion Interface
The expansion interface consists of three 90-pin connectors. Table 2-2
shows the interfaces each connector provides. For the exact pinout of the
connectors, refer to “ADSP-21375 EZ-KIT Lite Schematic” on page B-1.

LEDs and Push Buttons
General Purpose LEDs (LED1–8)
There are eight general-purpose LEDs on the board. Five LEDs are connected to the DPI interface, two LEDs are connected to the DAI interface,
and one LED is connected to FLAG3 of the processor. “LEDs and Push
Buttons” on page 1-15 summarizes the LED connections. To use a LED
connected to the DAI or DPI interface, program its respective register of
the processor. For more information on how to program the registers,
refer to the ADSP-2137x SHARC Processor Hardware Reference.
Power LED (LED9)
When LED9 is lit (green), it indicates that power is supplied to the board.
Reset LED (LED10)
When LED10 is lit (red), a master reset of all the major ICs is active.
USB Monitor LED (ZLED3)
The USB monitor LED (ZLED3) indicates that USB communication has
been initialized successfully, and you can connect to the processor using
an EZ-KIT Lite session. Once the USB cable is plugged into the board, it
takes approximately 15 seconds for the USB monitor LED to light. If the
LED does not light, try cycling power on the board and/or reinstalling the
USB driver.
the development software is actively communicating with
 When
the EZ-KIT Lite target board, the LED can flicker, indicating
communications handshake.

Push Buttons (SW8–11)
Four push buttons (SW8—11) are provided for general-purpose user input.
Two push buttons are connected to the FLAG pins of the processor, while
the other two are connected to the DAI of the processor. The push buttons are active high and, when pressed, send a high (1) to the processor.
Refer to “LEDs and Push Buttons” on page 1-15 for more information.
The push button enable switch ( SW7) is capable of disconnecting the push
buttons from corresponding processor pins. Refer to “Push Button Enable
Switch (SW7)” on page 2-13 for more information.
The push buttons and corresponding processor signals are summarized in
Table 2-9.

Board Reset Push Button (SW12)
The RESET push button (SW12) resets all of the ICs on the board. The only
exception is the USB interface chips. The chips are not reset when the
push button is pressed after the USB cable has been plugged in and communication initialized correctly with the PC. After USB communication
has been initialized, the only way to reset the USB is by powering down
the board.

VCO Select Jumper (JP1)
The voltage-controlled oscillator (VCO) select jumper (JP1) configures
the frequency selection of the on-board external PLL (U39). When JP1 is
installed, the VCO output frequency is multiplied by a factor of 1.0. Conversely, when uninstalled, the VCO output frequency is multiplied by a
factor of 0.5 or divided in half. The jumper settings are shown in
Table 2-10.

ELVIS Select Jumper (JP2)
The ELVIS select jumper (JP2) configures the EZ-KIT Lite’s connection
to an ELVIS station (see “ELVIS Interface” on page 1-13). When JP2 is
installed, connections to the push buttons and LED are re-directed to the
ELVIS station instead of the processor. The jumper settings are shown in
Table 2-11.
