Blackfin EZ-Extender Manual xix Notation Conventions xx Blackfin EZ-Extender Manual 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 analog-to-digital converters (ADCs) and mixed-signal HSC evaluation boards via the ADC/Mixed-Signal HSC interface. The ADC/Mixed-Signal 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 PPI and the HSC evaluation board. Additionally, the extender provides a RJ45 connector, which contains all of the SPI signals necessary to configure the control registers of capable HSC converters. For a block diagram of 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. Blackfin EZ-Extender Manual 1-1 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. With mixed-signal boards, the data direction can change and a programmable flag is used to change the direction in real time. The frame sync signals are dependent on the external user interface; thus, the functionality of the interface must be taken into consideration. For more information, refer to “System Architecture” on page 2-1 and “DIP Switches and Jumpers” on page 2-4. A list of ADC and mixed-signal evaluation boards compatible with the extender can be found at http://www.analog.com/processors/processors/blackfin/technicalLibrary/manuals/pdf/EZ-Extender_to_DSP_Su pported.pdf. Example programs can be found at ftp:// ftp.analog.com/pub/tools/patches/bf_extender_card.zip, when available. To learn more about Analog Devices data converters, go to http://www.analog.com. DAC HSC Interface The Blackfin EZ-Extender can connect to digital-to-analog converter (DAC) HSC evaluation boards via the DAC HSC interface. The DAC HSC interface consists of a 40-pin male header, which contains all of the control and data signals necessary to transfer data from the processor’s PPI to 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. 1-2 Blackfin EZ-Extender Manual EZ-Extender Interfaces 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. To configure the Blackfin EZ-Extender to connect to a DAC 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 and source of the data and frame synchronization signals. If your processor holds more than one PPI, the DAC interface allows you to communicate with either PPI0 or PPI1 of the processor. The direction of the frame sync signals is dependent on the target; thus, the functionality of the interface must be taken into consideration. For more information, refer to “System Architecture” on page 2-1 and “DIP Switches and Jumpers” on page 2-4. A list of DAC HSC evaluation boards compatible with the Blackfin EZ-Extender can be found at http://www.analog.com/processors/processors/blackfin/technicalLibrary/manuals/pdf/EZ-Extender_to_DSP _Supported.pdf. Example programs can be found at ftp:// ftp.anawhen available. To learn more about Analog Devices data converters, go to http://www.analog.com. log.com/pub/tools/patches/bf_extender_card.zip, Camera Interface The Blackfin EZ-Extender camera interface is a right-angle 32-pin connector with control signals compatible to the ITU-R BT.656 camera interface specification. Specifically, the extender’s camera interface is directly compatible with camera interface boards, such as the Omnivision OV6630AA evaluation module.

Blackfin EZ-Extender Manual 1-3 LCD Interface 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. To configure the Blackfin EZ-Extender to connect to a camera, 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 set the direction of the data and the frame sync signals. The direction of frame synchronization signals depends on the camera’s configuration. The data must be set as an input to the PPI port. For more information, refer to “System Architecture” on page 2-1 and “DIP Switches and Jumpers” on page 2-4. LCD Interface The LCD interface is intended to drive an LCD display device. A 32-pin, right-angle FLZ-type connector is provided to connect the data and control lines of commercially available LCD panels. For a block diagram of this interface, see Figure 2-1 on page 2-2. A timing and functional analysis is required to determine if a specific LCD can connect to the Blackfin EZ-Extender. An example of a display which does connect to the extender is the Sharp LQ058T5DRQ1 display. For more information about the Sharp LCD panel (part number LQ058T5DRQ1), go to http://www.sharpsma.com/fastfocus/nidetail.asp?t=DISPLAY&ck=f&p=PCPVTSBY3&n=2.

Blackfin EZ-Extender Block Diagram 2-2 Blackfin EZ-Extender Manual 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. For how to disable the TX_CLK sources, see “SMA Connector Clock Disconnect Jumper (P10)” on page 2-9 and “External Clock Disable Jumper (P37)” on page 2-10. The RX_CLK signal is generated by the target board. Both the TX_CLK and RX_CLK can be connected to the PPI_CLK signal as an input to the processor. See “Clock Routing Switch (SW2)” on page 2-5 for more information. The ADC/Mixed-Signal HSC interface and camera interface have two frame sync signals, FSYNC1 and FSYNC2. For information on how to set the direction and the source of these signals, refer to “Direction Control Switch (SW1)” on page 2-4 and “General Frame Sync Routing Switch (SW3)” on page 2-7. The LCD interface has two frame sync signals, FSYNC1_LCD and FSYNC2_LCD. These signals are always outputs, but it is possible set the source of the signals. For more information see, “LCD Frame Sync Routing Switch (SW4)” on page 2-8. The ADC/Mixed-Signal HSC interface and camera interface connect to the DATA_A[15:0] parallel bus. The DAC HSC interface and the LCD interface connect to the DATA_B[15:0] parallel bus. The DATA_A bus is attached to only the PPI0 bus, while DATA_B[15:0] can connect to either PPI0 or PPI1 busses. This allows access to all of the interfaces with a single PPI port or access to two separate interfaces with two PPI ports. For more information about the routing of the PPI data signals see, “PPI Data Routing Jumper (P36)” on page 2-9. To configure the direction of the DATA_A signals, see “Direction Control Switch (SW1)” on page 2-4. Blackfin EZ-Extender Manual 2-3 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. A designated DIP switch, SW1, provides an independent direction control for the DATA_A bus and the sync signals (FSYNC1 and FSYNC2) going to the camera interface and ADC/Mixed HSC interface, as illustrated in Figure 2-1 on page 2-2. Each of the signals can be hardwired to be either transmit or receive, or can be changed in real time using the PF0 processor programmable flag pin. the programmable flag is intended for direction control, L Ifensure the flag is not used for other purposes on the EZ-KIT Lite PF0 board (the motherboard). When the switch connects a direction control signal to ground (GND), the corresponding signal (or signals) being controlled is an input. The SW1 DIP switch settings are summarized in Table 2-1 through Table 2-3. Table 2-1.

When the SPI connector is not in use, remove the jumper to prevent any interfering with other devices on the SPI bus. SMA Connector Clock Disconnect Jumper (P10) The SMA connector (P11) provides the ability to input a clock from a signal generator or other clock source. This signal is first put though a buffer, as illustrated in Figure 2-1 on page 2-2. When the SMA connector is not in use, remove the jumper to prevent any interfering with other devices on the net. PPI Data Routing Jumper (P36) The flexibility of the EZ-Extender to be used with the Blackfin processor’s single and double PPI requires the PPI data signals to be routed accordingly. Figure 2-2 and Figure 2-3 show the data flow when P36 is installed and when it is not installed. connecting to the OV6630AA evaluation module, ensure L When that the jumper is not installed. The signals attached to P36 PPI1 are used as input by the camera.
