for differential analog signal output. A synchronous A/D
TRIGGER signal is provided to indicate the best sampling instant (rising slope of A/D TRIGGER signal). At
the end of the readout sequence the electronics produces an /EOS signal pulse.

High UV Sensitivity CCD Image Sensor S9840
Pixel frequency up to 1 MPixel per second
For 16 bit readout
Sensor chip socket for direct insertion on the PCB
Device input: sensor chip
Device output:
tec5 16 bit Front End Electronics with sensor interface type ‘Sensor_U2’ (FEE-1M /CCD-8)
PCB dimensions: 66 mm x 49 mm

General
The preamplifier electronics DZA-S9840 serves as an
interfacing component between the Hamamatsu CCD
Image Sensor and the Front End Electronics board of a
tec5 operation electronics. Typically, the CCD array is
plugged into the DIL-22 socket on the soldering side of
the PCB.
The preamplifier has to be supplied by five DC operating voltages applied to the power connector. These
external voltages are basically required for operation of
the CCD sensor. The tec5 DZA-S7030-4-P /PS board
with CAB-S9840 PS cable may be used to provide the
required operating voltages from a single 12 VDC input.
The interface to the Front End Electronics complies to
the tec5 specification ‘Sensor_U2’ (MICS-14 pin header
connector for PDA control signals, MICS-4 connector
for differential video signal) for direct interconnection to
FEE-1M.

For attaching external I C devices to the electronics, an
2
I C bus interface connector is integrated.
Based on the CLK and START input signals from the
FEE, the preamplifier board generates all signals required to read out the sensor chip. The analog video
signal from the sensor array is primed and processed

Digital Input Control Signals (HCT level):
START:
Initiates a readout cycle for the CCD
(active high, minimum length: one CLK
period).
CLK:
Master clock for CCD readout (frequency fm), has to be applied continuously.
Used to derive all internal clocking and
the output pixel rate.
Digital output signals (HCT level):
/EOS:
EndOfScan pulse output (active low,
duration: minimum one CLK pulse) to
signal the end of the array readout.
A/D TRIGGER: Pulse chain, signaling the sampling
instant for the video signal for each pixel during readout (active high, duration:
one CLOCK pulse). The video signal
level is held throughout the duration of
the pulse.

The DZA-S9840 is equipped with an I C interface addressing the on-board components EEPROM and tem2
perature sensor(s). Additional I C devices can be con2
nected via the I C connector.
