S8865-64G/-128G/-256G
S8866-64G-02/-128G-02
Photodiode array combined with signal
processing IC for X-ray detection
The S8866-64G-02/-128G-02 are photodiode arrays with an ampli¿er and a phosphor sheet attached to the active area for X-ray
detection. The signal processing circuit chip is formed by CMOS process and incorporates a timing generator, shift register, charge
ampli¿er array, clamp circuit and hold circuit, making the external circuit con¿guration simple. A long, narrow image sensor can
be con¿gured by arranging multiple arrays in a row.
As the dedicated driver circuit, the C9118 series (sold separately) is provided. (Not compatible with the S8865-256G.)

*8: Measured with a 2856 K tungsten lamp
*9: When the photodiode array is exposed to uniform light which is 50% of the saturation exposure, the photo response non-uiniformity
(PRNU) is de¿ned as follows:
PRNU = ΔX/X × 100 [%]
X: average output of all elements, ΔX: difference between X and the maximum or minimum output, whichever is larger.

1. The internal timing circuit starts operation at the falling edge of CLK immediately after a RESET pulse goes Low.
2. When the falling edge of each CLK is counted as “1 clock”, the video signal of the 1st channel appears between “18.5 clocks and 20.5
clocks”. Subsequent video signals appear every 4 clocks.
3. The trigger pulse for the 1st channel rises at a timing of 19.5 clocks and then rises every 4 clocks. The rising edge of each trigger pulse
is the recommended timing for data acquisition.
4. Signal charge integration time equals the High period of a RESET pulse. However, the charge integration does not start at the rise of a
RESET pulse but starts at the 8th clock after the rise of the RESET pulse and ends at the 8th clock after the fall of the RESET pulse.
After the RESET pulse next changes from High to Low, signals integrated within this period are sequentially read out as time-series
signals by the shift register operation. The rise and fall of a RESET pulse must be synchronized with the rise of a CLK pulse, but the rise
of a RESET pulse must be set outside the video output period. One cycle of RESET pulses cannot be set shorter than the time equal to
“16.5 + 4 × N (number of elements)” clocks.
5. The video signal after an EOS signal output becomes a high impedance state, and the video output will be inde¿nite.

2. When the falling edge of each CLK is counted as “1 clock”, the video signal of the 1st channel appears between “18.5 clocks and 20.5
clocks”. Subsequent video signals appear every 4 clocks.
3. To obtain video signals, extend the High period 3 clocks from the falling edge of CLK immediately after the RESET pulse goes Low, to a
20 clock period.
4. The trigger pulse for the 1st channel rises at a timing of 19.5 clocks and then rises every 4 clocks. The rising edge of each trigger pulse
is the recommended timing for data acquisition.
5. Signal charge integration time equals the High period of a RESET pulse. However, the charge integration does not start at the rise of
a RESET pulse but starts at the 8th clock after the rise of the RESET pulse and ends at the 8th clock after the fall of the RESET pulse.
After the RESET pulse next changes from High to Low, signals integrated within this period are sequentially read out as time-series

Set to A in the table below in most cases.
To serially read out signals from two or more sensors linearly connected, set the 1st sensor to A and the 2nd or later sensors to B.
The CLK and RESET pulses should be shared with each sensor and the video output terminal of each sensor connected together.

S8865-256G
Signals of channels 1 through 126 are output from CMOS1, while signals of channels 129 through 256 are output from CMOS2. The following two readout methods are available.
(1) Serial readout method
CMOS1 and CMOS2 are connected in serial and the signals of channels 1 through 256 are sequentially read out from one output line. Set
CMOS1 as in “A” in the table below, and set CMOS2 as in “B”. CMOS1 and CMOS2 should be connected to the same CLK and RESET lines,
and their video output terminals to one line.
(2) Parallel readout method
128 channel signals are output in parallel respectively from the output lines of CMOS1 and CMOS2. Set both CMOS1 and CMOS2 as in “A” in
the table below.

Check that pulse signals meet the required pulse conditions before supplying them to the input terminals.
Video output should be ampli¿ed by an operational ampli¿er that is connected close to the sensor.

Procautions for use
(1) The signal processing IC chip is protected against static electricity. However, in order to prevent possible damage to the IC chip, take
electrostatic countermeasures such as grounding yourself, as well as workbench and tools. Also protect the IC chip from surge voltages
from peripheral equipment.
(2) Gold wires for wire bonding are very thin, so they easily break if subjected to mechanical stress. The signal processing IC chip, wire
bonding section and photodiode array chip are covered with resin for protection. However, never touch these portions. Excessive force,
if applied, may break the wires or cause malfunction.
Blow air to remove dust or debris if it gets on the protective resin. Never wash them with solvent.
Signals may not be obtained if dust or debris is left or a scratch is made on the protective resin, or the signal processing IC chip or photodiode array chip is nicked.
(3) The photodiode array characteristics may deteriorate when operated at high humidity, so put it in a hermetically sealed enclosure or case.
When installing the photodiode array on a board, be careful not to cause the board to warp.
(4) The characteristics of the signal processing IC chip deteriorate if exposed to X-rays. So use a lead shield which is at least 1 mm larger all
around than the signal processing IC chip. The 1 mm margin may not be suf¿cient depending on the incident angle of X-rays. Provide an
even larger shield as long as it does not cover the photodiode active area. Since the optimal shield thickness depends on the operating
conditions, calculate it by taking the attenuation coef¿cient of lead into account.
(5) The sensitivity of the photodiode array chip decreases if continuously exposed to X-rays. The extent of this sensitivity decrease differs
depending on the X-ray irradiation conditions, so before beginning measurement, check how much the sensitivity decreases under the
X-ray irradiation conditions to be used.
Driver circuit C9118 series (sold separately)
The CMOS driver circuit is designed for the S8865-64/-64G and S8865-128/-128G photodiode arrays with ampli¿er.
The C9118 series operates a photodiode by just inputting two signals (M-CLK and M-RESET) and a signal +5 V supply.
The C9118 is intended for single use or parallel connections, while the C9118-01 is suitable for cascade connections.
Features
Single power supply (+5 V) operation
Operation with two input signals (M-CLK and M-RESET)
Compact: 46 × 56 × 5.2 t mm
