DESCRIPTION
The sensor has an image area having 2048 x 2064 pixels,
split readout registers at both top and bottom with charge
detection amplifiers at both ends. The pixel size is 15
m
square. The image area has four separately connected
sections to allow full-frame, frame transfer, split full frame or
split frame-transfer modes. Depending on the mode, the
readout can be through 1, 2 or 4 of the output circuits. A
gate-controlled drain is also provided to allow fast dumping
of unwanted data.
The output amplifier is a two-stage type designed to give
minimum noise at pixel rates as high as 5 MHz. The low
output impedance of 400
simplifies the interface with
external electronics. Dummy outputs are also available to
facilitate common mode rejection.
To achieve maximum full-well capacity, a four-phase image
clocking sequence should be used. The detailed clock
sequences are given in this data sheet.
The readout register is designed to accommodate at least
four image pixels of charge, but the maximum signal then
exceeds the capacity of the output circuit unless the output
is operated in low responsivity mode.
Specifications are guaranteed and tested at –25
C.
Quoted performance parameters given here are “typical”
values. Specification limits are shown later in this data
sheet.

OTHER VARIANTS
The CCD230-42 is available with a 3 mm fibre-optic stud.
Back-illuminated and NIMO versions of the basic CCD230
are also available. Devices with other formats (up to 8192 x
3172 pixels) can also be provided. A variant is also available
with an alternative very low noise amplifier but with lower
charge handling capacity (CCD231).
