The sensor board also has 8 charge-sensitive amplifier arrays each having 300 ch amplifiers with a horizontal shift register. Analog video signals are amplified as the charge on each video line by 2400 ch charge amplifiers with CDS (Correlated Double Sampling) circuits added, and are output each of 8 amplifier arrays. The control board converts the analog video signal into a 12-bit digital signal and outputs it to an external frame grabber through the 12-bit parallel port. 5760000 EXTERNAL POWER SUPPLY A.vdd, D.vdd, V (7.5) (not attached) IntExt BINNING (bin0, bin1) TIMING PULSE GENERATOR AMP ARRAY No. 8 OSCILLATOR ExtTrgLemo ExtTrgGrb Vsync Hsync Pclk BIAS GENERATOR BUFFER AMP PROCESSING AMP BUFFER AMP PROCESSING AMP A/D FIFO VIDEO OUTPUT (12 BIT DIGITAL) Note: Signals are read out in order of pixel number.

The National Instruments IMAQ PCI-1424 (NI parts No. 777662-01) frame grabber with optional memory 64 MB (NI parts No. 920130-64) has been verified to successfully acquire 12-bit digital images from C7942SK-05. You can utilize the demonstration software that comes with the frame grabber as a simple viewer, to acquire and save an image. To do so, refer to the frame grabber user's guide for how to use the camera information file for the demonstration software. * Power source: A.vdd = +5.0 0.1 V (700 mA), D.vdd = +5.0 0.1 V (1000 mA), V (7.5) = 7.5 0.5 V (100 mA) Please use a series power supply. (Avoid using a switching power supply.) A power cable (terminated with an FGG.2B.307.CLAD92Z plug at one end and open at the other end; 2 m; see Table 2.), an external trigger cable (terminated with an FFA.OS.302.CLAC37 plug at one end and open at the other end; 5 m; see table 3.) and an earth cable (AWG 18; 4 m) comes supplied with C7942SK-05. An optional frame grabber cable for interface with the 36-pin receptacle (see Table 1) on C7942SK05 is also available for synchronous signal, video output and external control. 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 but it causes 0.1 V approx. drop. Therefore the voltage at the power 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. To supply the synchronous signal through ExtTrgGrb, apply high level of TTL to ExtTrgLemo and IntExt, or leave them without connection. On the contrary, to use ExtTrgLemo, set high level to ExtTrgGrb and IntExt, or leave them without connection. The earth terminal must be connected to a stable earth point to eliminate noise from surroundings.

(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 Xrays 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 make a replacement or repair of any defective product due to defects in workmanship or materials used in manufacture. It 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 6 million Roentgen (less than 150 kVp) even within the warranty period. * As described above, flat panel sensors have limited resistance to radiation. This must be taken into account when using a flat panel sensor under continuous irradiation (in-line non-destructive inspection, etc.) When using flat panel sensors in non-destructive inspection equipment, please contact us and provide information such as irradiation conditions.
