Max Unit Clock pulse frequency f(CLK) 0.2 - 5 MHz Video rate VR - f(CLK) - Hz Output impedance*5 Zo - 150 - Ω Current consumption*6 I - 20 - mA *5: Video signal output terminal (10-pin) An increase in the current consumption at the video output terminal also increases the chip temperature and so causes the dark current to rise. To avoid this, connect a buffer amplifi er to the video output terminal so that the current fl ow is minimized. *6: f(CLK)=5 MHz Recommended terminal voltage (Ta=25 °C) Parameter Symbol Min. Typ.

In addition, the glass used in the light path of the previous C10988MA-01 is not used in the C12880MA, making it extremely compact.

  • The packaging of the C12880MA is electrically conductive, so be careful when designing the circuit to avoid short circuit cause d by contact with a circuit pattern.
  • If external force is repeatedly applied to the lead pins, this may damage the lead pins.
  • To prevent damage due to soldering, be careful of the soldering temperature and time. As a general guide, fi nish soldering within 3.5 seconds at 350 °C or less when soldering by hand, or within 10 seconds at 260 °C or less when using a solder bath.

The shift register starts operation at the rising edge of CLK immediately after ST goes low. The integration time can be changed by changing the ratio of the high and low periods of ST. If the fi rst TRG pulse after ST goes low is counted as the fi rst pulse, the Video signal should be acquired at the rising edge of the 89th TRG pulse.

Micro-spectrometer C12880MA Operation example thp(ST)=1.2 μs tlp(ST)=75 μs ST tpi(ST)=76.2 μs KACCC0772EA This is an operating example when the clock pulse frequency is set to maximum (video data rate is also set to maximum), the tim e per scan to minimum, and the integration time to maximum. ∙ Clock pulse frequency [f(CLK)] = Video data rate = 5 MHz ∙ Start pulse cycle [tpi(ST)] = 381/f(CLK) = 381/5 MHz = 76.2 μs ∙ Low period of start pulse min. [tlp(ST)] = 375/f(CLK) = 375/5 MHz = 75 μs ∙ High period of start pulse [thp(ST)] = Start pulse cycle [tpi(ST)] - Low period of start pulse min. [tlp(ST)] = 76.2 μs - 75 μs = 1.2 μs Integration time is equal to the high period of start pulse + 48 cycles of clock pulses, so it will be 1.2 μs + 9.6 μs = 10.8 μs.
