1 USING SHARC AUDIO EZ-EXTENDER This chapter describes the SHARC Audio EZ-Extender package contents, configuration, installation procedure, and analog audio interface. The information is presented in the following order. • “Package Contents” on page 1-2 Describes the product’s package contents. • “SHARC Audio EZ-Extender Default Configuration” on page 1-3 Describes the board’s default configuration. • “SHARC Audio EZ-Extender Setup” on page 1-5 Provides the board’s setup procedure.
Package Contents Your SHARC Audio EZ-Extender package contains the following items. • SHARC Audio EZ-Extender board • VisualDSP++ Installation Quick Reference Card • CD containing: D VisualDSP++ software D SHARC Audio EZ-Extender debug software D Example programs D SHARC Audio EZ-Extender Manual (this document) • 3.5 mm stereo headphones • 6-foot RCA audio cable • 6-foot 3.5 mm/RCA x 2 Y-cable • 3.
SHARC Audio EZ-Extender Default Configuration The EZ-Extender system contains ESD (electrostatic discharge) sensitive devices. Electrostatic charges readily accumulate on the human body and equipment and can discharge without detection. Permanent damage may occur on devices subjected to high-energy discharges. Proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Store unused EZ-Extender boards in the protective shipping package.
Figure 1-1.
SHARC Audio EZ-Extender Setup It is important to set up all components of the system containing the SHARC Audio EZ-Extender, then apply power to the system. The following procedure is recommended for the correct setup. Power your system after these steps are completed: 1. Read the audio interface section in this chapter—the text provides an overview of the interface capabilities. 2. Read “System Architecture” on page 2-2 to understand physical connections of the daughter board.
The audio interface connections are shown in Figure 2-2; more details can be found in “SHARC Audio EZ-Extender Schematic” on page B-1. The three codec chips (referred to as “AD1939A”, “AD1939B”, and “AD1939C”) connect in parallel to the serial peripheral interface (SPI) port of the ADSP-21469 SHARC processor via the DPI pins. The SPI port of the processor is used to adjust volume and other audio parameters of each of the three codecs.
The number of channels can be set up in the control registers and is dependent on the sample rate. As the sample rate increases, the number of possible channels decreases. • At 96 kHz, the AD1939 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.

SHARC Audio EZ-Extender Hardware Reference Figure 2-2 is a block diagram of the audio interface; the diagram illustrates how the serial ports are interfaced to the processor and AD1939 codecs on a mating SHARC EZ-Board. The block diagram is a high-level diagram and does not show the voltage translation circuitry or clock buffers. The schematic pages are available in “SHARC Audio EZ-Extender Schematic” on page B-1.
System Architecture The analog audio interface consists of three AD1939 audio codec ICs (referred to as “AD1939A”, “AD1939B”, and “AD1939C”), which use up to six serial ports (SPORTs) of the processor. All of the clock and frame sync signals of the processor are driven by the master AD1939 codec (AD1939A). The master codec can run in either Time-Division Multiplexed (TDM) mode or Integrated Interchip Sound (I2S) mode at a 48 KHz, 96 KHz, or 192 KHz sample rate in both modes using only two serial ports.
SHARC Audio EZ-Extender Hardware Reference Configuration Switches This section describes operation of the configuration switches. Before using the SHARC Audio EZ-Extender, follow the steps documented in the readme text files in the \214xx\Examples\SHARC Audio EZ-Extender directories of VisualDSP++ 5.0 update 7 or later. The switch locations are shown in Figure 2-3. Switches on the bottom side of the EZ-Extender board are shown with a dashed line. Figure 2-3.
Configuration Switches Audio Loopback Switches (SW1–6) The audio loopback switches (SW1—6) are intended for test purposes only. The switches loop-back any analog output signal generated from an AD1939 codec’s digital-to-analog converter (DAC) circuit to analog-to-digital converter (ADC) circuit: • SW1—2 are designed for the master codec (AD1939A) • SW3—4 are designed for the secondary codec (AD1939B) • SW5—6 are designed for the third codec (AD1939C) By default, switches SW1–6 are all OFF.
