Description  
The FXA 1012 is a colour frame-transfer CCD image sensor designed  
for consumer digital photography applications. The combination of  
high speed and a high linear dynamic range of over 10 true bits  
makes this device the perfect solution for use in compact high quality  
imaging applications. Two modes of operation provide both a  
monitoring image for LCD screens, and a full resolution, zero-smear  
still image with excellent colour rendition. The device structure is  
shown in figure 1.

Architecture of the FXA 1012  
The FXA 1012 consists of an open image section and a storage  
section with an optical light shield. An output register and amplifier  
are located below the storage section for read-out.  
through the storage section to the horizontal output register. In the  
monitoring mode subsampling of the image is performed at the  
image-to-storage transition and the subsampled image is stored in  
the storage section. The stored image is shifted one line at a time  
into the horizontal output register.  
The optical centres of all pixels in the image section form a square  
grid.The image area has RGB Bayer colour filter pattern.The charge  
is generated and integrated in the image section. This section is  
controlled by four image clock phases (A1 to A4). After the integration  
time the image charge is shifted one line at a time to the storage  
section.  
In the next active line time the pixels are transported towards the  
output amplifier. Four clock phases (C1 to C4) control the pixel  
transport in the output register. In the output amplifier the charge  
packets are dumped one by one on a floating diffusion area. The  
voltage of this area is sensed and buffered by a three-stage FET  
source-follower. Figure 2 shows the detailed internal structure.  
The storage section is controlled by four storage clock phases (B1  
to B4). In the still mode the image information is transported straight

Operational modes  
The FXA 1012 is designed for high-resolution digital photography  
with real time monitoring at reduced resolution.Two different modes  
of operation make this possible.  
In the monitoring mode, images with reduced vertical resolution are  
produced that are suitable for LCD displays.These images can have  
for example, 120, 240 or 256 lines at up to 40 images per second.  
In the still picture mode the high-resolution image is read-out directly.  
A mechanical shutter ensures a 100% smear-free image with a  
resolution of 1600 (H) x 1280 (V).

Application information  
Current handling  
One of the purposes of VPS is to drain the holes that are generated  
during exposure of the sensor to light. Free electrons are either  
transported to the VRD connection and, if excessive (from over-  
exposure), free electrons are drained to VNS. No current should  
flow into VPS. During overexposures a total current 0.5 to 1mA  
through VPS may be expected.The PNP emitter follower in the circuit  
diagram (figure 9) serves these current requirements.  
VNS drains superfluous electrons as a result of overexposure. In  
other words, it only sinks current.During overexposures a total current  
of 0.5 to 1mA through VNS may be expected. The NPN emitter  
follower in the circuit diagram meets these current requirements.  
The clamp circuit, consisting of the diode and electrolytic capacitor,  
enables the addition of a Charge Reset (CR) pulse on top of an  
otherwise stable VNS voltage. To protect the CCD, the current  
resulting from this pulse should be limited.This can be accomplished  
by designing a pulse generator with a rather high output impedance.  
a current source or more simply with a resistance to GND. In order  
to prevent the output (which typically has an output impedance of  
about 400 Ohm) from bandwidth limitation as a result of capacitive  
loading, load the output with an emitter follower built from a high-  
frequency transistor. Mount the base of this transistor as close as  
possible to the sensor and keep the connection between the emitter  
and the next stage short. The CCD output buffer can easily be  
destroyed by ESD. By using this emitter follower, this danger is  
suppressed; do NOT reintroduce this danger by measuring directly  
on the output pin of the sensor with an oscilloscope probe. Instead,  
measure on the output of the emitter follower. Slew rate limitation is  
prevented by avoiding a too-small quiescent current in the emitter  
follower; about 10mA should do the job. The collector of the emitter  
follower should be decoupled properly to suppress the Miller effect  
from the base-collector capacitance. A CCD output load resistor of  
3.3 ktypically results in a bandwidth of 95MHz.  
Decoupling of DC voltages  
Device protection  
All DC voltages (not VNS, which has additional CR pulses as  
described above) should be decoupled with a 100nF decoupling  
capacitor. This capacitor must be mounted as close as possible to  
the sensor pin. Further noise reduction (by bandwidth limiting) is  
achieved by the resistors in the connections between the sensor  
and its voltage supplies.The electrons building up the charge packets  
that will reach the floating diffusion only add up to a small current,  
which will flow through VRD. Therefore a large series resistor in the  
VRD connection may be used.  
The output buffer or VNS of the FXA 1012 is likely to be damaged if  
VPS rises above SFD or RD at any time.This danger is most realistic  
during power-on or power-off of the camera.  
Never exceed the maximum output current. This may damage the  
device permanently. The maximum output current should be limited  
to 6mA. Be especially aware that the output buffers of these image  
sensors are very sensitive to ESD damage.  
Because of the fact that our CCDs are built on an n-substrate, we  
are dealing with some parasitic NPN transistors. To avoid activation  
of these transistors during switch-on and switch-off of the camera,  
we recommend the application diagram of figure 9.  
Output  
To limit the on-chip power dissipation, the output buffer is designed  
with open source output.The output should therefore be loaded with

peripheral circuits for the FXA 1012 is suggested:  
An image sensor is a MOS device which can be destroyed by electro-  
static discharge (ESD). Therefore, the device should be handled  
with care.  
• Pulse Pattern Generator  
The PPG (pulse pattern generator) delivers all the pulses, at logic  
level, to drive the vertical clocks of the CCD. For this sensor, the  
PPG is included in the DSP SAA8122 or separately in the Timing  
Generator SAA8103.  
Always store the device with short-circuiting clamps or on conductive  
foam.Always switch off all electric signals when inserting or removing  
the sensor into or from a camera (the ESD protection in a CCD  
image sensor is less effective than the ESD protection of standard  
CMOS circuits).  
• Vertical Drivers + DC/DC Converter  
The vertical drivers convert the 3.3V or 5V logic pulses from the  
PPG to 12V analog pulses to drive the vertical clocks of the CCD.  
The recommended driver is the Philips TDA9991.  
Being a high quality optical device, it is important that the cover  
glass remain undamaged.When handling the sensor, use fingercots.  
• CDS - AGC - ADC  
To remove the protective tape from the cover glass, use the following  
procedure:  
• do not scratch or tear off the protective tape before mounting.  
• peel off the tape slowly.  
• the use of an ionised air blower is recommended when peeling off  
the tape.  
• once peeled off, do not reuse the tape.  
The combined CDS (correlated double sampling) - AGC (automatic  
gain control) and ADC (10 bit analog-to-digital convertor) is the  
easiest way to link the output of the CCD to a DSP (digital signal  
processor). Philips Semiconductors # TDA8783  
• DSP  
A dedicated DSP has been developed that can handle the image  
format and different modes of the FXA 1012. Philips  
Semiconductors # SAA8122.  
To clean stains from the package surface, use a cotton stick soaked  
in ethanol. Wipe carefully in order not to scratch the glass surface.  
Special modes of operation  
Dry rubbing of the cover glass may cause electro-static discharges  
which can destroy the device.  
Monitor mode with 240 lines vertical resolution is achieved with 1:5  
subsampling, yielding 1200/5 = 240 lines. When 1:4 subsamlping is  
applied, an image with 288 lines vertical resolution is obtained.  
Soldering information  
The CCD package temperature must not exceed 150°C. Soldering  
iron temperature should be under 300°C when mounting a CCD on  
a printed circuit board. Aim for a soldering time of 3 seconds per  
pad. Use a soldering iron that has an adjustable temperature control  
function (that is grounded) that holds the soldering iron tip at a  
constant temperature.
