s Block diagram (C7942CA-02)
C7942CA-02 is a lightweight and compact flat panel sensor consisting of a sensor board and a control board. The sensor board
also has 8 charge-sensitive amplifier arrays each having 300 ch amplifiers with a horizontal shift register. Analog video signals
are amplified as the charge on each video line by 2400 ch charge amplifiers with CDS (Correlated Double Sampling) circuits
added, and are output each of 8 amplifier arrays. The control board converts the analog video signal into a 12-bit digital signal and
outputs it to an external frame grabber through the 12-bit parallel port.
