| IMAGE SENSOR InGaAs linear image sensor G9201 to G9204 series Image sensor for DWDM wavelength monitor G9201 to G9204 series InGaAs linear image sensors are specifically designed as detectors for monitoring WDM in optical communications. These linear image sensors consist of an InGaAs photodiode array with each pixel connected to a charge amplifier array comprised of CMOS transistors, a CDS circuit, an offset compensation circuit, a shift register and a timing generator. These sensors deliver high sensitivity and stable operation in the near infrared spectral range. The package is hermetically sealed for high reliability and the window has an anti-reflective coating for efficient light detection. Signal processing circuits on the CMOS chip allow selecting a feedback capacitance (Cf) of 10 pF or 0.5 pF by supplying an external voltage. The image sensor operates over a wide dynamic range when Cf=10 pF and delivers high gain when Cf=0.5 pF.

A CDS circuit greatly reduces this reset noise by holding the signal immediately after reset to find the noise differential. *2: Timing generator Different signal timings must be properly set in order to operate a shift register. In conventional image sensor operation, external PLDs (Programmable Logic Devices) are used to input the required timing signals. However, G9201 to G9204 series image sensors internally generate all timing signals on the CMOS chip just by supplying CLK and RESET pulses. This makes it simple to set the timings. *3: G9203-256D and G9204-512D are not available for C7557. *4: For G9203-256D and G9204-512D specifications, see the separate data sheets available from Hamamatsu. s Spectral response 1.0 T=25 C T= -10 C (Typ.)
