June 20, 2001 TM-75/76 High-Resolution CCD Camera Operation Manual 1 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 highresolution camera features an advanced Hyper-HAD* interline transfer 1/2" CCD imager, and offers many standard and optional features at a very affordable price.
PAGE 8
Page 2 Introduction The camera can be reset at random timing to restart. It will also take an external trigger signal to control shutter and reset timing for asynchronous image capturing. • Low lag/high resistance to image burning Because the CCD is highly resistant to image burning, the camera may be exposed to bright objects for a long period of time. Because a “smear” phenomenon may occur when shooting a very bright object, an infrared cutoff filter is standard to obtain a clear picture.

This will power the camera up. 2.2.3 Attaching the Video Output Most users utilize the BNC connector for video output from the camera. Connect the output from the camera to the input of your monitor, VCR, or switching device. The input of the monitor should be balanced for 75Ω termination. Standard RG-59 type coaxial cable should carry a full video signal for up to 500 feet.

PAGE 18
Page 12 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. HD and VD input is TTL level and the input impedance is 75Ω. 3.2.
PAGE 19
Page 13 TM-75/76 External Signals 4 TM-75/76 External Signals This section explains how the external signals (HD and VD) and shutter trigger signal (TRIG) must be fed in 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
Page 14 TM-75/76 External Signals For External HD, VD sync mode or Reset-Restart mode selection, please refer to Section 3.1.1, “Mode Selection,” on page 8. Mode switch F2 must be set to ON for R-R mode and keep it OFF for normal HD, VD external sync mode. FIGURE 5. HD and Reset-Restart (VD) Relationship EXT.
PAGE 21
Page 15 TM-75/76 External Signals 4.5 Trigger Pulse for Pulse-Width Shutter Control In pulse width shutter control mode, the leading edge and trailing edge of TRIG must be synchronized with external HD. The duration must be longer than 1H. If TRIG does not meet these conditions, the exposure time may vary depending on the trigger position in one field to another field. FIGURE 7. Proper Pulse Width Control EXT. HD TRIG FIGURE 8. Improper Pulse Timing for Width Control EXT.
PAGE 22
Page 16 Operation Mode 5 Operation Mode 5.1 No Shutter Cyclic (Continuous Sync) Operation In Cyclic operation mode, the camera generates its own synchronization signal by itself. It continuously (cyclically) transfers photo charge at every VD (Vreset) in internal or external HD, VD sync mode. Since no discharge occurs, the one full frame (1/30 sec or 1/25 sec) is the exposure time for both fields in frame accumulation mode.

The discharge and transfer repeats in every field at a predefined shutter speed.
PAGE 24
Page 18 Operation Mode 5.3 Snapshot Reset-Restart Shutter (Donpisha Shutter) In this mode the shutter trigger pulse (TRIG) should be 150 nsec (two pixel clock) or wider. Snapshot mode is similar to Pulse Position mode. However the leading edge of TRIG pulse in snapshot mode immediately produces discharge pulse without delay (means Donpisha= no delay) and starts exposure, which enables very high speed shutter up to over 1/1,000,000 sec (1 µsec exposure). It can, in theory, go to a 70 nsec exposure time.
PAGE 25
Page 19 Operation Mode 5.4 Pulse Position Reset-Restart Shutter The shutter trigger pulse (TRIG) is required to be wider than 1H (>70 µsec) for this operation. Like continuous shutter mode, the last discharge pulse occurs as external shutter control. The position is determined at 1H after the detection of the TRIG pulse edge. The transfer (read out) occurs at 9.5H (14.5H for the TM-76) from reset-restart VD leading edge. The minimum exposure time is 0.5H (34.4 µsec).
