    Introduction 1.1 Product Description The TM-75 is specifically designed to be a replacement for SONY’s XC-75 camera. It is an inexpensive yet high-quality camera that meets a variety of application requirements. This miniaturized high- resolution camera features an advanced Hyper-HAD interline transfer 1/2"...

  • Page 8: Functional Options

    Image capture can begin within a fraction of a second after turning on the camera. The power consumption is only 2.3W, 190mA @12V. • Camera mounting flexibility The TM-75/76 has tapped M3 holes on the top and bottom. A tripod mount is available as an optional accessory. • Three-year warranty The CCD solid-state image sensor allows the camera to maintain a superior performance level indefinitely while requiring virtually no maintenance.

    Page 3 Introduction 1.5 Interfacing to Frame Grabbers The TM-75/76 camera can be connected to a frame grabber using either the 12-pin connector or the BNC connector on the rear panel of the camera. 1.6 System Configuration Figure 1 (below) presents a typical system configuration for the TM-75.

  • Page 10: Installation

    2.2 Camera Setup 2.2.1 Connector Pin Configurations The TM-75/76 has a 12-pin connector for power input. In general, Pin #1 is Ground and Pin #2 is +12V DC. The other pins handle a number of other input and output functions, as shown in the table below.

  • Page 11: Power Supply And Power Cable

    2.2.2 (b) PULNiX Power Cables If you are using PULNiX power cables, such as the 12P-02S, please refer to the appropriate pin-out diagram. The color coded leads use Gray for Ground and Yellow for +12V DC. TM-75/76 High-Resolution CCD Camera...

  • Page 12: Figure 2. 12P-02S Interface Cable (Optional)

    The 12-pin connector is keyed and will only fit in one orientation. Follow these directions to properly attach the power cable to the camera connector: Rotate the connector while applying slight pressure until the keyways line up. Press the connector into place until firmly seated. TM-75/76 High-Resolution CCD Camera...

    75Ω termination. Standard RG-59 type coaxial cable should carry a full video signal for up to 500 feet. To output the video and input the power and sync to a camera over a single cable, use the PULNiX multi-conductor cables, such as the 12P-02S, etc. The mini coaxial leads in PULNiX multi-conductor cables are designed for short runs of no longer than 100 feet.

    VD, internal VD is automatically generated. 3.1.3 Field and Frame Modes The standard factory setting for the TM-75/76 camera is FRAME MODE. The field and frame integration mode is selectable using the #2 switch of the mode switch inside the camera. The frame integration is used to separate all CCD pixels.

  • Page 16: Figure 3. Field/Frame Diagram

    Field mode, however, Frame mode has the disadvantage of showing vertical Moire. Frame mode should be used in applications that need strobe lighting, because full frame resolution is achieved in this mode. For higher pixel definition such as gauging and sub-pixel interpolation, Frame mode operation is recommended. TM-75/76 High-Resolution CCD Camera...

    2 is binned with row 3, row 4 with row 5, and so on. 3.2.2 Cyclic (Continuous) Shutter Mode With rotary switch shutter control, the TM-75/76 operates at the internally predefined shutter speeds. Each field output is exposed for the same period. The shutter control varies the substrate discharge timing.

  • Page 18: Reset-Restart Mode

    Operation 3.2.3 External Sync Mode TM-75/76 accepts standard RS-170 external sync, which is defined as horizontal sync (HD) and vertical sync (VD). The phase-locked loop jitter is designed to be the minimum (< 5ns) in this category using the latest PLL chip. The wide capture range enables the camera to operate at an extended temperature range (optional) of -35°C to 65°C.

  • Page 19: Tm-75/76 External Signals

    External sync (HD, VD sync) and Reset-Restart operation. 4.1 External HD When external HD is supplied to pin #6 of the 12-pin connector, the TM-75/76 automatically switches the clock to phase-lock to the external clock via HD PLL (phase lock loop). The PLL detects the leading edge of external HD and Phase compare with the internal HD.

  • Page 20: External Trigger (Trig) And Internal Sampling Clock

    4.4 External Trigger (TRIG) and Internal Sampling Clock To ensure stable operation without the influence of jitter, the TM-75/76 samples shutter trigger pulse (TRIG) by internal sampling clock (LCLK) and detects the low to high level change of TRIG. The sampling occurs only at HD leading edge timing to generate the internal TRIG as shown below.

  • Page 21: Trigger Pulse For Pulse-Width Shutter Control

    For snapshot mode (Donpisha shutter), the TRIG pulse width can be wider than just 2 pixel clocks wide (>150nsec) since this mode only requires pixel clock data strobing. The internal TRIG is generated at any random point and stays high until transfer gate pulse is completed. TM-75/76 High-Resolution CCD Camera...

  • Page 22: Operation Mode

    In Field 2, the pairs change to row 2 and 3, 4 and 5 and so on. This field mode accumulation is effective for electronic shutter applications as it generates twice as sensitive an image as frame mode. The electronic shutter output is always one field image per shutter. TM-75/76 High-Resolution CCD Camera...

  • Page 23: Continuous Shutter

    The discharge pulses occur in every horizontal line (in blanking) and stop at a predefined shutter timing in one field. The duration between the last discharge and transfer determines the exposure time. Continuous Shutter Timing FIGURE 11.
