(It is not necessary to switch above timing shown in figure.) But care should be taken not to make more than two switches to "L" level at the same time. 6 2001-10-15 TIMING CHART 1 TCD2301C 7 2001-10-15 TIMING CHART 2 TCD2301C 8 2001-10-15 TIMING CHART 3 TCD2301C 9 2001-10-15 TCD2301C TIMING REQUIREMENTS 10 2001-10-15 TCD2301C TIMING REQUIREMENTS (Cont.)

Window Glass The dust and stain on the glass window of the package degrade optical performance of CCD sensor. Keep the glass window clean by saturating a cotton swab in alcohol and lightly wiping the surface, and allow the glass to dry, by blowing with filtered dry N2. Care should be taken to avoid mechanical or thermal shock because the glass window is easily to damage. 2. Electrostatic Breakdown Store in shorting clip or in conductive foam to avoid electrostatic breakdown. CCD Image Sensor is protected against static electricity, but interior puncture mode device due to static electricity is sometimes detected. In handing the device, it is necessary to execute the following static electricity preventive measures, in order to prevent the trouble rate increase of the manufacturing system due to static electricity. a. Prevent the generation of static electricity due to friction by making the work with bare hands or by putting on cotton gloves and non-charging working clothes. b. Discharge the static electricity by providing earth plate or earth wire on the floor, door or stand of the work room. c. Ground the tools such as soldering iron, radio cutting pliers of or pincer. It is not necessarily required to execute all precaution items for static electricity. It is all right to mitigate the precautions by confirming that the trouble rate within the prescribed range. 3. Incident Light CCD sensor is sensitive to infrared light. Note that infrared light component degrades resolution and PRNU of CCD sensor. 4. Soldering Soldering by the solder flow method cannot be guaranteed because this method may have deleterious effects on prevention of window glass soiling and heat resistance. Using a soldering iron, complete soldering within ten seconds for lead temperatures of up to 260C, or within three seconds for lead temperatures of up to 350C. 14 2001-10-15 TCD2301C <Application note> EVEN-ODD UNBALANCE When High-speed draiving standard level of odd-even bits is often unbalanced. For that reason when high-speed draiving CCD you should put a damping resistance in input pin. 1. WAVEFORM (Sample and Hold ON) 2.
