EVBUM2357/D KSC-1000 Timing Generator Board User's Manual Timing Generator Board Description This Timing Generator Board is designed to be used as part of a two-board set, used in conjunction with a CCD Imager Evaluation Board. ON Semiconductor offers a variety of CCD Imager Boards that have been designed to operate with this Timing Generator Board. For more information on the available Imager Evaluation Boards, please contact ON Semiconductor. The Timing Generator Board generates the timing signals necessary to operate Imager Boards, and also provides the power required by these Imager Boards via the board interface connector (J6). In addition the Timing Generator Board performs the signal processing and digitization of the analog output of the Imager Board. Up to two analog outputs of the Imager Board are connected to the Timing Generator Board via coaxial cables. The KSC−1000 Timing Generator chip provides multiple pixel-rate, line-rate, and frame rate clocks and control signals to operate Truesense Imaging CCD image sensors. The KSC−1000 is able to operate many different Interline, Full-Frame, and Linear CCD image sensors. POWER_ON_DELAY EVAL BOARD USER’S MANUAL The Timing Generator Board contains an Altera Programmable Logic Device (PLD) that can be In-System-Programmed (ISP) with code that is imager specific. This provides flexibility to operate many different Imager Boards with the same Timing Generator Board. The Timing Generator Board has a digital Input interface to the Altera device that can be used to support various modes of operation depending on imager-specific Altera code. The digital input interface also includes a serial interface to the KSC−1000 and AFE parts on the Timing Generator Board so that adjustments may be made to their operation, overriding the pre-programmed default operating conditions.

General guidelines for these requirements are shown in Table 1; refer to the appropriate Timing Specification for the input power requirements of a particular Evaluation Boardset. Table 1. POWER SUPPLY INPUT REQUIREMENTS Power Supplies Minimum Typical Maximum Unit +5 V_MTR Supply 4.9 − 5 800 5.1 − V mA −5 V_MTR Supply −5.1 − −5 50 −4.9 − V mA VPLUS Supply 18.0 20 (Imager Board Dependent) 21.0 V mA VMINUS Supply −18.0 −20 (Imager Board Dependent) −21.0 V mA TIMING GENERATOR BOARD ARCHITECTURE OVERVIEW Power-On Delay/Board Reset The following sections describe the functional blocks of the Timing Generator Board (See Figure 1 for a block diagram). The POWER_ON_DELAY signal provides a reset signal to the Altera Programmable Logic Device (PLD) on power-up, or when the BOARD RESET button (S1) is pressed. The delay is generated by an RC network into a Schmitt trigger, and is approximately 400 ms, allowing power supply voltages to stabilize on the board. When the POWER_ON_DELAY signal goes high, the PLD will perform its normal power-up initialization sequence, as detailed in the applicable Timing Specification. Power Connector The J3 power connector provides the necessary power supply inputs to the Timing Generator Board. The connector also provides the VPLUS and VMINUS power supplies. These supplies are not used by the Timing Generator Board but are needed by the CCD Imager Boards. The Timing Generator Board simply routes these power supplies from the power connector to the board interface connector. System Clock The System clock is used to generate the pixel rate clocks. The pixel rate timing signals operate at a frequency that is divided down from the System clock frequency. The exact pixel rate frequency is Altera code dependent, but is limited to 1/2 the frequency of the System clock. Power Supply Filtering Power supplied to the board is de-coupled and filtered with ferrite beads and capacitors in order to suppress noise. For best noise performance, linear power supplies should be used to provide power to the boards. Table 2.

This is an optional feature; no external digital inputs are required for board operation. Any TTL-compatible digital controls may be used to control these lines. While it is recommended that these inputs range between +3.3 V (HIGH) and 0 V (LOW), voltages up to +5.0 V are acceptable. The digital input connector (J7) connects optional remote digital control signals to the evaluation board. These control signals, DIO[15..0], can be used to adjust the operating mode of the evaluation board. The function of the digital inputs depends on the Altera firmware programmed for a particular Evaluation Boardset, and is detailed in the www.onsemi.com 2 EVBUM2357/D Altera PLD The digital input control lines to the board are buffered. The input pins to the buffer IC’s are weakly held low by pull down resistors to GND. Therefore, with no digital inputs, the default level of the control lines is all zeros. A three-wire serial interface is also provided on the J7 input connector. The Altera PLD is programmed to decode the serial datastream, and steers the datastream to the KSC−1000 and the AFE chips as necessary. Therefore the KSC−1000 and each of the two AFE chips may be adjusted independently of one another via the serial interface, overriding the default settings stored in the Altera PLD. This is an optional feature, and is not required for board operation. The Programmable Logic Device (PLD) is an Altera Flex 10K series part. Paired with an EPC2 configuration EPROM, the Altera device is In System Programmable (ISP) via a 10-pin JTAG header (J2) located on the board. In this way, the Altera device is programmed with imager-specific code to operate the Imager Board to which the Timing Generator Board will be connected. The code implemented in the Altera PLD is specific to each CCD Imager Board configuration, and is detailed in the associated Timing Specification document. At a minimum, the Altera PLD must provide these functions: • Decode and steer serial input data to the correct device; • Program the KSC−1000 with default settings; • Program the AFE chips with default settings. Configuration Switches There are eight switches on the board that can be used to adjust the operating mode of the Timing Generator Board. The function of the switches depends on how the Altera device is programmed for a particular Evaluation Boardset, and is detailed in the associated Altera Code Timing Specification. In addition to these functions, the Altera PLD may provide auxiliary timing and control functions for a particular CCD Imager Board. Refer to the appropriate Timing Specification for details. Serial Input Steering When the three-wire serial input to the Timing Board is used, the Altera PLD decodes the addressing of the serial input, and steers the datastream to the correct device. The serial input must be formatted so that the Altera PLD can correctly decode and steer the data to the correct device. The first 3 bits in the datastream are the Device Select bits DS[2..0], sent MSB first, as shown in Figure 2. The Device Select bits are decoded as shown in Table 3. JTAG Header This 10-pin header (J2) provides the user with the ability to reprogram the Altera PLD in place via Altera’s BYTEBLASTER programming hardware. Purchasers of an Evaluation Board Kit may, at their discretion, make changes to the Altera code firmware. ON Semiconductor can only support firmware developed and supplied by ON Semiconductor. Changes to the Altera code firmware are at the risk of the customer. When programming the Altera PLD via the JTAG interface, the Imager Board must be disconnected from the Timing Board, by removing the Board Interface Cable before power is applied. If the Imager Board is connected to the Timing Board during the reprogramming of the Altera PLD, damage to the Imager Board may occur. Table 3. SERIAL INPUT DEVICE SELECT Device Select DS[2..0] Serial Device 000 PLD 001 AFE1 Integrate Output Connector This output header (J4) provides a signal that is high during the integration time period. INTEGRATE can be used to synchronize an external shutter or LED light source with the integration time period. The INTEGRATE signal, buffered by a transistor, is also connected to the Digiflex Camera connector (J1). This feature is optional, and the connector is not populated. 010 AFE2 011 KSC−1000 100 (Imager Board Dependent) 101 (Imager Board Dependent) 110 (Imager Board Dependent) 111 (Imager Board Dependent) The next bit in the datastream is the Read/Write bit (R/W). Only writing is supported; therefore this bit is always LOW. The definition of next four bits in the datastream depends on the device being addressed with the Device Select bits. For the KSC−1000 device, they are Register Address bits A[3..0] LSB first. For the AD9845A or AD9840A AFE, they are Register Address bits A[2..0], LSB first, followed by a Test bit which is always set LOW. The remaining bits in the bitstream are Data bits, LSB first, with as many bits as are required to fill the appropriate register. Image Sensor LVDS Drivers Timing signals are sent to the Imager Board via the board interface connector (J6) using Low Voltage Differential Signaling (LVDS) drivers. LVDS combines high-speed connectivity with low noise and low power. Board Interface Connector This 80-pin connector (J6) provides both the timing signals and the necessary power to the CCD Imager Boards from the Timing Generator Board. www.onsemi.com 3 SLOAD SDATA SCLK … Dn D4 D3 D1 D2 D0 A3 (or Test) A2 A1 R/W A0 DS0 DS2 DS1 EVBUM2357/D ÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌ ÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌ ÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌ Figure 2. Serial Input Timing to each CCD Imager Board configuration, and are detailed in the associated Timing Specification document. There are several PLD connections, GIO[2..0], that are connected only to test points (TP8, TP7, and TP6). These may be configured as PLD outputs or inputs, for extra monitoring or control. The Altera PLD receives the serial datastream, decodes the Device Select address contained in the first 3 bits, and sets the appropriate SLOAD line LOW. The remaining datastream is then read in real time by the selected device. The Altera PLD does not do any checking of the datastream for correctness; it merely steers the data to the appropriate device. Auxiliary PLD Functions The Altera PLD may provide auxiliary timing and control functions for a particular CCD Imager Board. In addition to the Configuration switches, Remote Digital Inputs, and 3-wire Serial Interface, the inputs to the PLD include timing signals from the KSC−1000, and an auxiliary shutter control input from the (optional) J1 Digiflex Camera connector. The PLD outputs include: PLD[2..0], auxiliary outputs which are routed to the Board Interface connector (J6); HD_TG and VD_TG, timing controls signals to the KSC−1000; and ARSTZ, an asynchronous reset to the KSC−1000. These inputs and outputs allow the Altera PLD to monitor the CCD timing, and to control auxiliary functions as needed. KSC−1000 Default Programming Upon power-up, or whenever the BOARD_RESET button is pressed, the Altera PLD automatically programs the registers of the KSC−1000 to their default settings via the three-wire serial interface. The default settings are specific to each CCD Imager Board configuration, and are detailed in the associated Timing Specification document. AFE Default Programming Upon power-up, or whenever the BOARD_RESET button is pressed, the Altera PLD automatically programs the registers of the KSC−1000 to their default settings via the three-wire serial interface. The default settings are specific Table 4.

Each AFE is independently addressable through the Altera PLD, and therefore can be adjusted independently. Each of the two signal processing channels is designed to process an analog video signal input from a CCD Imager Board. The analog video signal is buffered by an operational amplifier. This amplifier is in a non-inverting configuration with a gain of 1.25. The output of the amplifier is then AC-coupled into the input of the AFE chip. Since the amplitude of AFE input is limited, care must be taken to adjust the gain of the Imager Board signal prior to the AFE input. The Imager Board for a particular CCD image sensor has been designed to deliver a video signal with the correct amplitude to the Timing Board, such that, when the AFE is correctly configured, optimum performance is achieved. Digital Image Data LVDS Drivers Digitized image data and synchronization timing signals are sent to the computer frame-grabber hardware via the 100-pin SCSI output connector (J10) using Low Voltage Differential Signaling (LVDS) drivers. LVDS combines high-speed connectivity with low noise and low power. SCSI Digital Output Connector This 100-pin connector (J10) provides digitized image data and synchronization timing signals to the computer frame-grabber hardware. The output connector interfaces directly to the National Instruments PCI−1424 frame-grabber, providing two channels of 12 bit output data in parallel in LVDS differential format. The connector also provides the three necessary PCI−1424 frame-grabber synchronization signals in LVDS differential format. AD984X Analog Front End (AFE) Device The Timing Generator Board has two analog input channels, each consisting of an operational amplifier buffer and an Analog Front End (AFE) device. The AFE chip processes the video signal, then performs the A/D conversion and outputs 10 or 12 bits of digital information per pixel. The Timing Generator Board supports the AD984X family of AFE devices offered by Analog Devices Inc. There are several variants in the AD984X family. The Timing Generator Board is populated differently depending on which AFE device is being used. The various assembly configurations are shown in Table 5. When using the AD9840 (10-bit, 40 MSPS) AFE, R56, R57, R63, and R64 are installed to tie what would be the least significant bits in a 12-bit system to AGND. Otherwise, these components are not installed. The AD9840A and AD9845A AFE parts have three modes of operation with respect to the analog input signal: CCD MODE, AUX1 MODE, and AUX2 MODE. The Timing Generator Board only supports the CCD MODE. Refer to the Analog Devices AD9845A or AD9840A Specification Sheet for details. KSC−1000 Timing Generator The KSC−1000 controls the overall flow of the evaluation board operation. The TG outputs include the CCD clocks signals, AFE timing signals, and Frame Grabber synchronization signals. The KSC−1000 is configured by programming Registers, Frame Tables, and Line Tables.
