PREFACE

Thank you for purchasing the ADSP-21375 EZ-KIT Lite®, Analog Devices, Inc. evaluation system for ADSP-21375 SHARC® processors.

The 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 IO 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 VisualDSP++® development environment to test the capabilities of the ADSP-21375 SHARC processors. The VisualDSP++ development environment gives you the ability to perform 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

Analog Audio

The AD1835A 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 via the DAI port. The DAI interface pins can be configured to transfer serial data from the AD1835A codec in either time-division multiplexed (TDM) or two-wire interface mode (TWI). For more information on the AD1835A connection to the DAI, see “DAI Interface” on page 2-4.

The master input clock (MCLK) for the AD1835A device can be generated by the on-board 12.288 MHz oscillator or can be supplied by one of the DAI pins of the processor. Using one of the pins 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.

The AD1835A codec can be configured as a master or as a slave, depending on the DIP switch settings. In master mode, the AD1835A 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 information on how to set up the mode, refer to “Codec

2-2 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 the 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 gives 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 the flash memory. For information about configuring the boot modes, see “Boot Mode and Clock Ratio Select

Switch (SW2)” on page 2-10.

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 1-7 for more information about accessing the 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.

System Architecture

DAI Interface

The digital application interface (DAI) pins connect 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 allows to route the DAI pins to different internal peripherals in various combinations.

The DAI pins connect 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.

To use the DAI for a different purpose, disable any signal driving the DAI pin with a switch (see “Codec Setup Switch (SW3)” on page 2-11). In addition, the

SW3 switch allows flexible routing of the 12.288 MHz audio

oscillator’s output signal. By default, this 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), as well as the 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 connect 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 allows to route the DPI pins to different internal peripherals in various combinations.

System Architecture

The DPI pins connect to the SPI flash memory, the SPI interface 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.

To use the DPI for a different purpose, disable any signal driving the DPI pins 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

using the signal elsewhere on the board.

All of the DPI signals are available externally via the expansion interface connectors (J1–3), as well as the 0.1” spaced header P3. The pinout of these connectors can be found in “ADSP-21375 EZ-KIT Lite Schematic”

on page B-1.

FLAG signals are available externally via the expansion interface con-

nectors (J1–3). The pinout of these 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 the 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. The mechanical dimensions of the connectors can be obtained from Tech-

nical or Customer Support.

System Architecture

Limits to the current and to the interface speed must be taken into consideration when using the expansion interface. The maximum current limit is dependent on the capabilities of the used regulator. Additional circuitry also can add extra loading to signals, decreasing their maximum effective speed.

[

Analog Devices does not support and is not responsible for the effects of additional circuitry.

JTAG Emulation Port

The JTAG emulation port allows an emulator to access the internal and external memory of the processor through a 6-pin interface. The JTAG emulation port of the processor also connects to the USB debugging interface. When an emulator connects to the board at ZP4, the USB debugging interface is disabled. This is not a standard connection of the JTAG interface.

For information about the standard connection of the interface, see EE-68 published on the Analog Devices Web site. For more information about the JTAG connector, see “JTAG Header (ZP4)” on page 2-25. To learn more about available SHARC processor emulators, go to

Codec Setup Switch (SW3)

The codec setup switch (SW3) can be used to change the routing of some signals going to the AD1835A codec and to set up the communication protocol of the codec.

SW3 positions 1 and 2 determine the clock routing for the audio oscillator

to the codec and to the processor. Figure 2-5 illustrates how the switch positions 1 and 2 connect on the board. In the default position, route the

DAI_P17 pin to DAI_P6 (in software) to clock the AD1835A codec.

SW3 position 3 determines if the AD1835A device is a master or a slave. If

the AD1835A is a master, the device’s serial interface generates the frame sync and clock signals necessary to transfer data. When the device is a slave, the processor must generate the frame sync and clock signals. By default, position 3 is ON, and the AD1835A codec generates the control signals.

SW3 position 4 disconnects the AD1835A codec’s ADC_DATA pin from the

DAI interface. This is useful when the DAI interface connects to another device.
