PREFACE Thank you for purchasing the Blackfin EZ-Extender®, Analog Devices (ADI) extender board to the EZ-KIT Lite® evaluation system for ADSP-BF533 and ADSP-BF561 Blackfin® processors. The Blackfin processors are embedded processors that support a Media Instruction Set Computing (MISC) architecture. This architecture is the natural merging of RISC, media functions, and digital signal processing (DSP) characteristics towards delivering signal processing performance in a microprocessor-like environment.
The board extends the capabilities of the evaluation system by providing a connection between the parallel peripheral interface (PPI) of the ADSP-BF533 processor (the PPI0 and PPI1 interfaces of the ADSP-BF561 processor), an Analog Devices high-speed converter (HSC) evaluation board, a camera evaluation board, and an LCD display device.

1 EZ-EXTENDER INTERFACES The Blackfin EZ-Extender board offers the following interfaces. • “ADC and Mixed-Signal HSC Interface” • “DAC HSC Interface” • “Camera Interface” • “LCD Interface” The following sections describe each extender interface. ADC and Mixed-Signal HSC Interface The Blackfin EZ-Extender can connect to an analog-to-digital converter (ADCs) and a mixed-signal HSC evaluation board via the ADC/mixed-signal HSC interface.
DAC HSC Interface To configure the Blackfin EZ-Extender to connect to an ADC or mixed-signal HSC evaluation board, first determine the source of the PPI clock. To learn about possible clock settings, refer to “Clock Routing Switch (SW2)” on page 2-5. It is also necessary to determine the direction of the data and frame synchronization signals. The direction is dependent upon the type of the board to which you connect. With ADC boards, it is necessary to set up the data driver on the extender as a receiver.
EZ-Extender Interfaces the DAC evaluation board. Your extender kit includes the cable used to make a connection. For more information about this interface, see Figure 2-1 on page 2-2. Before using the Blackfin EZ-Extender, familiarize yourself with the documentation and schematics of the target board and the EZ-KIT Lite. For example, on the EZ-KIT Lite, it may be necessary to disable other devices on the PPI, route the PPI clocks, and disable the push buttons.
LCD Interface OV6630AA evaluation module. To learn more about the OV6630AA evaluation module, go to http://www.ovt.com. For a block diagram of the camera interface, see Figure 2-1 on page 2-2. Before using the Blackfin EZ-Extender, familiarize yourself with the documentation and schematics of the target board and the EZ-KIT Lite. For example, on the EZ-KIT Lite, it may be necessary to disable other devices on the PPI, route the PPI clocks, and disable the push buttons.
EZ-Extender Interfaces Please note that the power for the backlight feature of the LCD must be provided by the customer. Information on the backlight inverter module (part number LXM1614-14-11) needed to connect to the LCD panel is available at http://www.chipdocs.com/pndecoder/datasheets/MSEMI/LXM1614-14-11.html?ReR=IN. The part number of the connector on the EZ-Extender is JST32FLZ-SM1-R-TB.

2 EZ-EXTENDER HARDWARE REFERENCE This chapter describes the hardware design of the Blackfin 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 2-4 Describes the function of the configuration DIP switches. System Architecture A detailed block diagram of the Blackfin EZ-Extender is shown in Figure 2-1.
System Architecture Figure 2-1.
EZ-Extender Hardware Reference The EZ-Extender holds two clock signals, TX_CLK and RX_CLK. The TX_CLK signal is used as an output to the interface you are using. The TX_CLK signal can be generated in three ways: applying a signal via an SMA connector, populating a socket with an oscillator, or using a 27 MHz signal provided by the EZ-KIT Lite. Only one of these sources can be used at a time, the other sources must be disabled.
DIP Switches and Jumpers 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 settings effect on your application. Direction Control Switch (SW1) The PPI interface is bidirectional and half-duplex.

EZ-Extender Hardware Reference General Frame Sync Routing Switch (SW3) Frame synchronization signals FSYNC1 and FSYNC2 get configured through the SW3 DIP switch settings, as illustrated in Figure 2-1 on page 2-2. The FSYNC1 signal can be set by either the PF2 programmable flag or the processor’s PPI0_SYNC1 signal. The FSYNC2 signal can be set by either the PF3 programmable flag or the PPI0_SYNC2 signal. Table 2-6 and Table 2-7 depict the available options.
DIP Switches and Jumpers LCD Frame Sync Routing Switch (SW4) Frame synchronization signals FSYNC1_LCD and FSYNC2_LCD get configured through the SW4 DIP switch settings, as illustrated in Figure 2-1 on page 2-2. The FSYNC1_LCD signal can be set by the PF2 programmable flag, PPI0_SYNC1, or PPI1_SYNC1 signal. The FSYNC2_LCD signal can be set by the PF3 programmable flag, PPI0_SYNC2, or PPI1_SYNC2 signal. Figure 2-8 and Figure 2-9 depict the available options.
EZ-Extender Hardware Reference Table 2-9. FSYNC2_LCD Source Settings (Cont’d) SW4 Position 4 PF2 SW4 Position 5 PPI0_SYNC2 SW4 Position 6 PPI1_SYNC2 FSYNC2_LCD Source ON OFF ON FSYNC2_LCD – – – All other configurations should not be used = PF3 MISO Disconnect Jumper (P7) The SO signal of the SPI connector (J1) is driven by a buffer to the processor’s MISO signal, as illustrated in Figure 2-1 on page 2-2.
DIP Switches and Jumpers Figure 2-2. P36 Not Installed Data Flow Figure 2-3. P36 Installed Data Flow External Clock Disable Jumper (P37) The EZ-KIT Lite provides a 27 MHz clock, which can be used as a transmit clock for all of the interfaces as illustrated in Figure 2-1 on page 2-2. When the 27 MHz clock is not being used, remove the jumper to prevent the TX_CLK signal from being driven. For information about other transmit clock sources, see “Clock Routing Switch (SW2)” on page 2-5.
