Optical component layout
Besides a CMOS image sensor chip integrated with an optical slit by etching
technology, the C12880MA employs a reflective concave blazed grating formed
by nanoimprint. In addition, the glass used in the light path of the previous
C10988MA-01 is not used in the C12880MA, making it extremely compact.

A/D output is the sum of the sensor and circuit
offset outputs and the sensor dark output.
A/D output is the output with dark output is subtracted
when light is input. The difference between the ideal value
and typical example contains a measurement error. The
smaller the A/D output, the larger the measurement error.

Precautions
· The packaging of the C12880MA is electrically conductive, so be careful when designing the circuit to avoid short circuit caused 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, finish 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.

*11: The shortest period required to output the video signals from all pixels.
*12: The integration time equals the high period of ST plus 48 CLK cycles.
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 first TRG pulse after ST goes low is counted as the first pulse, the Video signal should be acquired at the rising edge of the
89th TRG pulse.

Operation example
This is an operating example when the clock pulse frequency is set to maximum (video data rate is also set to maximum), the time 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
thp(ST)=1.2 μs
tlp(ST)=75 μs
ST
tpi(ST)=76.2 μs
KACCC0772EA
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.

Driver circuit for micro-spectrometer C13618
The C13618 is a driver circuit that the C12880MA or C12880MA-10 can be mounted on. It
has an A/D converter that can be used to obtain digital data (16-bit) by applying an external power supply and drive signal. Using this driver circuit with the user’s circuit board
having LVDS level and 3.3 V level I/O ports eliminates the need for designing analog circuits and video output conversion circuits.
