s Block diagram
C9252DK-14 is a lightweight and compact flat panel sensor consisting of a sensor board and a control board. The sensor board
has 16 charge-sensitive amplifier arrays each having 78 ch amplifiers with a horizontal shift register. Analog video signals are
amplified as the charge on each video line by 1248 ch charge amplifiers with CDS (Correlated Double Sampling) circuits added,
and are output each of 16 amplifier arrays. The control board converts the analog video signal into a 13-bit digital signal and
outputs it to an external frame grabber through the 13-bit parallel port.
