Sony ICX098AK Datasheet

Description

The ICX098AK is a diagonal 4.5mm (Type 1/4)
interline CCD solid-state image sensor with a square
pixel array which supports VGA format. Progressive
scan allows all pixels signals to be output
independently within approximately 1/30 second.
Also, the adoption of monitoring mode allows output
to an NTSC monitor without passing through the
memory. This chip features an electronic shutter with
variable charge-storage time which makes it possible
to realize full-frame still image without a mechanical
shutter. High resolution and high color reproductivity
are achieved through the use of R, G, B primary color
mosaic filters. Further, high sensitivity and low dark
current are achieved through the adoption of HAD
(Hole-Accumulation Diode) sensors.

This chip is suitable for applications such as electronic
still cameras, PC input cameras, etc.

Features

• Progressive scan allows individual readout of the

image signals from all pixels.

• High horizontal and vertical resolution (both approx.

400TV-lines) still image without a mechanical

shutter.

• Horizontal drive frequency: 12.27MHz

• No voltage adjustments (reset gate and substrate

bias are not adjusted.)

sensitivity, low dark current

• Continuous variable-speed shutter

• Low smear

• Excellent antiblooming characteristics

• Horizontal register: 3.3V drive

• 14-pin high precision plastic package (enables dual-surface standard)

VRGLH is the maximum value and VRGLL is the minimum value of the coupling waveform during the period from
Point A in the above diagram until the rising edge of RG. In addition, VRGL is the average value of VRGLH and
VRGLL.

VRGL = (VRGLH + VRGLL)/2

Assuming VRGH is the minimum value during the interval twh, then:

VφRG = VRGH – VRGL

Negative overshoot level during the falling edge of RG is VRGLm.
