Block diagram
C9728DK is a lightweight and compact flat panel sensor consisting of a sensor board and a control board. The sensor board also
has 8 charge-sensitive amplifier arrays each having 132 channel amplifiers with a horizontal shift register. Analog video signals
are amplified as the charge on each video line by 1056 ch charge amplifiers with CDS (Correlated Double Sampling) circuits
added, and are output each of 8 amplifier arrays.

System requirements
To operate C9728DK at full performance, the following system and peripherals are required.
· PC: IBM full compatible PC with USB 2.0 running on Windows XP or later operating system. The south bridge of on-board Intel
chip set should be ICH4 or later.
· Power source: A.vdd = +5.0 ± 0.1 V (600 mA), D.vdd = +5.0 ± 0.1 V (900 mA)
Please use a low noise series power supply. (Avoid using a switching power supply.) A pigtail power cable (terminated with a
JST J-C9-2C plug at one end and open at the other end; 2 m; see Table 1.), an trigger cable (ter minated with an FGG.0B. 304.
CLAD56 plug at one end and open at the other end; 5 m; see table 2.) and an ear th cable (AWG 18; 4 m) come supplied with
C9728DK.
The voltages described above are specified at the flat panel sensor side. The impedance of the power cable attached with the
flat panel sensor is low enough b ut it causes 0.1 V appro x. drop. Therefore the voltage at the pow er source side should be set 0.1
V higher than the voltage specified above.
Install a noise filter on the AC power input line to prevent surges on the AC line.
Driver software, DLL and sample software are also attached. The USB receptacle is mini-B type. The mini-B USB cable is not
attached.
The earth terminal must be connected to a stable earth point to eliminate noise from surroundings.

Notice
· Do not subject the Flat Panel Sensors to strong vibration or shock. (Strong shock such as drop impacts may cause permanent
damage to these sensors.)
· Users must take responsibility for implementing X-ray shielding safety measures to avoid the risk of X-ray exposure.
· Data listed in this datasheet was measured at the time of shipment. Characteristics may vary somewhat due to exposure to X-
rays so take proper countermeasures such as making periodic image correction.
· This product is warranted for a period of 12 months after the date of the shipment.
The warranty is limited to replacement or repair of any defective product due to defects in wor kmanship or mater ials used in
manufacture. The warranty does not cover loss or damage caused by natural disaster, misuse (including modifications and any
use not complying with the environment, application, usage and storage conditions described in this datasheet), or total
radiation dose over 45000 Roentgen (less than 18 keV) even within the warranty period.
C9728DK conforms to European EMC directives:
EN61326 Class A.
