The information is presented in the following sections. • “ADC HSC Interface” on page 1-1 • “Breadboard Area” on page 1-2 ADC HSC Interface The SHARC EZ-Extender can connect to analog-to-digital high-speed converter (ADC HSC) evaluation boards via the ADC HSC interface. The ADC HSC interface consists of a 40-pin female header, which contains all of the control and data signals necessary to transfer data between the processor’s Parallel Data Access Port (PDAP) and the HSC evaluation board. Additionally, the extender provides a RJ45 connector, which contains all of the Serial Peripheral Interconnect (SPI) signals necessary to configure the control registers of capable high-speed converters. For a block diagram of the ADC HSC interface, see Figure 2-1 on page 2-2. Before using the SHARC EZ-Extender, familiarize yourself with the documentation and schematics of the target board and the ADSP-21262 EZ-KIT Lite. For example, on the EZ-KIT Lite, it may be necessary to disable other devices on the PDAP or disable the push buttons. To configure the SHARC EZ-Extender to connect to an ADC HSC evaluation board, determine the source of the PDAP clock and the direction of general-purpose signals, DAI_P15_GP1 and DAI_P16_GP2. To learn about possible clock settings, refer to “Direction/Clock Source Control Switch SHARC EZ-Extender Manual 1-1 Breadboard Area (SW1)” on page 2-3. The setup of the general-purpose signals DAI_P15_GP1 and DAI_P16_GP2 is dependent on the specific ADC HSC evaluation board being interfaced; thus, the board’s model must be taken into consideration. The data bus of the EZ-Extender must be enabled before data is read. Enable the data bus by a memory read from address 0x160 0000, which the AD[15:0] pins set up as the External Port. Then, the AD[15:0] pins can be set up in PDAP mode. A list of ADC boards compatible with the extender can be found at http://www.analog.com/processors/processors/blackfin/technicalLibrary/manuals/pdf/EZ-Extender_to_DSP_Supported.pdf. Contact Technical Support for information about available examples. To learn more about Analog Devices data converters, go to http://www.analog.com. Breadboard Area SHARC EZ-Extender broadens the range of the EZ-KIT Lite applications by providing surface mounted (SMT) footprints for breadboard capabilities and access to all of the pins on the EZ-KIT Lite’s expansion interface. 1-2 SHARC EZ-Extender Manual 2 EZ-EXTENDER HARDWARE REFERENCE This chapter describes the hardware design of the SHARC EZ-Extender . The following topics are covered. • “System Architecture” on page 2-1 Describes the configuration of the extender and explains how the board components interface with the processor and EZ-KIT Lite. • “DIP Switches and Jumpers” on page 2-3 Describes the function of the configuration DIP switches and jumpers. System Architecture A detailed block diagram of the SHARC EZ-Extender is shown in Figure 2-1. Note that the arrow in the bidirectional driver symbols denotes the direction of the driver when in transmit mode. The bidirectional driver is in transmit mode when the direction pin is pulled high. Use the diagram in conjunction with information in “DIP Switches and Jumpers” on page 2-3 section of this manual to configure your SHARC EZ-Extender . Before using the SHARC EZ-Extender , familiarize yourself with the documentation and schematics of the target board and the ADSP-21262 EZ-KIT Lite. For example, on the EZ-KIT Lite, it may be necessary to disable other devices on the PDAP or disable the push buttons.

SHARC EZ-Extender Block Diagram The block diagram in Figure 2-1 shows that each clock and general-purpose signal attached to the ADC HSC interface is configured depending on how the interface operates. 2-2 SHARC EZ-Extender Manual EZ-Extender Hardware Reference The EZ-Extender has two clock signals, TX_CLK and RX_CLK. The TX_CLK signal is used as an output and can be generated in three ways: by applying a signal via an SMA connector, by using the RX_CLK signal, or by populating a socket with an oscillator. Only one of these sources can be used at a time, the other sources must be disabled. For more information on how to disable the TX_CLK sources, see “SMA Connector Clock Disconnect Jumper (P10)” on page 2-5. The RX_CLK signal is generated by the target board. Both the TX_CLK and RX_CLK can connect to the processor’s clock-in signal (DAI_P2_CLOCKIN) as an input. See “Direction/Clock Source Control Switch (SW1)” on page 2-3 for more information. The ADC interface has two general-purpose signals, DAI_P15_GP1 and DAI_P16_GP2. The evaluation board with which the extender interfaces determines how these signals are set up. For information on how to set the direction and the source of these signals, refer to “Direction/Clock Source Control Switch (SW1)” on page 2-3. The ADC interface connects to the PDAP of the ADSP-21262 processor. The PDAP is multiplexed with the address and data bus. To avoid bus contention with the memory devices on the EZ-KIT Lite, the driver connected to the data bus of the ADC must be enabled. For more information about enabling the data bus, see “ADC HSC Interface” on page 1-1. DIP Switches and Jumpers The following section describes the function of all of the jumpers and switches on the EZ-Extender. Before connecting the extender, make sure you understand each possible setting effect on your application. Direction/Clock Source Control Switch (SW1) A designated DIP switch, SW1, provides an independent direction control for the general-purpose signals (DAI_P15_GP1 and DAI_P16_GP2), as illustrated in Figure 2-1 on page 2-2. Each signal can be hardwired to be either SHARC EZ-Extender Manual 2-3 DIP Switches and Jumpers transmit or receive, or can be changed in real time using the DAI_P18 processor pin. If the DAI_P18 processor pin is intended for the direction control, ensure the pin is not used for other purposes on the EZ-KIT Lite board. When the SW1 switch connects a direction control signal to ground (GND), the corresponding signal (signals) is (are) controlled as input. The direction control functionality is summarized in Table 2-1. Table 2-1. DAI_P15_GP1/DAI_P16_GP2 Direction Control Settings SW1 Position 3 SW1 Position 5 SW1 Position 4 SW1 Position 6 DAI_P15_GP1 Direction DAI_P16_GP2 Direction OFF OFF EZ-KIT Lite is transmitter OFF ON DAI_P18 sets the direction: 0 = EZ-KIT Lite is receiver 1 = EZ-KIT Lite is transmitter ON OFF EZ-KIT Lite is receiver ON ON Do not use The source of the PDAP clock input signal, DAI_PP2_CLOCKIN, is configured through positions 1 and 2 of the DIP switch SW1, as illustrated in Figure 2-1 on page 2-2. The switch settings are summarized in Table 2-2. Table 2-2. PDAP Clock-in Source Settings 2-4 SW1 Position 1 RX_CLK SW1 Position 2 TX_CLK DIA_P2_CLOCKIN Source OFF OFF Not generated by the EZ-Extender OFF ON In this configuration, the TX_CLK signal must be generated by one of the user configured clock sources. ON OFF RX_CLK ON ON RX_CLK. In this configuration, the RX_CLK signal is also routed to the TX_CLK to be used as an output. SHARC EZ-Extender Manual EZ-Extender Hardware Reference MISO Disconnect Jumper (P6) The SO signal of the SPI connector (J2) is driven by a buffer to the processor’s MISO signal, as illustrated in Figure 2-1 on page 2-2. When the SPI connector is not in use, remove the P7 jumper to prevent the signal from interfering with other devices on the SPI bus. SMA Connector Clock Disconnect Jumper (P10) The SMA connector (P7) enables a clock input from a signal generator or from other clock source. The input signal is directed though a buffer, as illustrated in Figure 2-1 on page 2-2. When the SMA connector is not in use, remove the P7 jumper to prevent the buffer from driving other signals on the net.
