Driver circuit for InGaAs linear image sensor C10820 Driver circuit for InGaAs linear image sensor (G9494 series) The C10820 is a driver circuit designed for the G9494 series high-speed InGaAs linear image sensors. The C10820 generates clock signal and reset signal needed to drive the InGaAs linear image sensor, and amplifies and outputs the video signal of the InGaAs linear image sensor while subtracting the offset from the video signal. Features Applications Simple signal input operation (only digital signal inputs for START and M-CLK pulses, and +5 V and +15 V power supplies required) Control and data acquisition of InGaAs linear image sensor (G9494 series) High gain setting suitable for low-level-light Compact size Absolute maximum ratings (Ta=25 °C) Parameter Analog supply voltage Digital supply voltage Digital input voltage Operating temperature*1 Storage temperature*1 Symbol +VA -VA +VD Topr Tstg Value +18 -18 +7 +VD 0 to +50 -20 to +70 Unit V V V V °C °C *1: No condensation Specifications (Ta=25 °C) Parameter Analog supply voltage Analog supply current Digital supply voltage Digital supply current High level Digital input Low level Start pulse width Clock frequency Digital rise/fall times Date rate VIDEO saturation output Symbol ±VA +IA -IA +VD +ID VIH VIL Tpwst fM-CLK tTLH/tTHL fV Vsat Min. ±14.5 4.75 3.5 0 125 0.01 - Typ. ±15.0 70*2/120*3 -30 5.0 3 2 14 2 - Max. ±15.5 120*2/180*3 -40 5.25 5 5.5 1.5 4 25 4 4 Unit V mA mA V mA V ns MHz ns MHz V *2: When mounted with the G9494-256D *3: When mounted with the G9494-512D www.hamamatsu.com 1 Driver circuit for InGaAs linear image sensor C10820 Block diagram SW3: CF-SELECT +5 VA CH-SW Vref INP InGaAs image sensor Vdd + + +5 VA VR1 + GATE-SW +5 VA Regulator -5 VA Reference voltage generator + + +15 V +5 V +15 V -15 V -15 V VR2 + Vss VIDEO-E VIDEO-O (VIDEO) M-CLK START TRIGGER EOS Timing generator CLK-O ( CLK) RESET-O (RESET) TRIG-O (AD-TRIG) Cf CLK-E TRIG-E RESET-E SW2: S-SELECT +5 VA (512 ch) (256 ch) + ×1 VIDEO ×1~3 KACCC0496EA Timing chart G9494-256D M-CLK START RESET* 4 M-CLK 4 M-CLK 12 M-CLK Integration time CLK-ODD* 1 2 (only CLK-ODD is output when used with G9494-256D) 4 8 O-1 O-2 O-3 O-4 O-5 O-253 O-254 O-255 O-256 VIDEO 1 EOS 2 3 4 5 253 254 255 256 TRIGGER * Internal signal M-CLK START KACCC0497EA 2 Driver circuit for InGaAs linear image sensor C10820 G9494-512D M-CLK START RESET* Integration time 8 M-CLK 8 M-CLK 1 2 3 12 M-CLK 4 8 CLK-ODD* CLK-EVEN* O-1 O-2 O-3 O-4 O-5 E-1 E-2 E-3 E-4 O-253 O-254 O-255 O-256 E-253 E-254 E-255 E-256 VIDEO 1 2 3 4 5 6 7 8 9 505 506 507 508 509 510 511 512 EOS TRIGGER * Internal signal M-CLK START KACCC0498EA Note: When used with the G9494-256D, M-CLK equals CLK-ODD. When used with the G9494-512D, M-CLK is divided by 2, and CLK-ODD and CLK-EVEN are generated with complementary timing and output while each is shifted by half the CLK period. This means that the G9494-256D and 9494-512D operate at the same data rate when a same frequency M-CLK is input.

The active area of the InGaAs linear image sensor must be light-shielded during this adjustment. Turn the trimmer clockwise to increase the offset, or turn it counterclockwise to reduce the offset. In either case, adjust the offset so that the VIDEO signal becomes higher than GND. O Circuit gain adjustment: VR2 Use the VR2 trimmer to adjust the circuit gain according to the incident light level. Turn the trimmer clockwise to increase the gain, or turn it counterclockwise to reduce the gain. Note that the DC offset also varies when the gain is changed by VR2, so readjustment to the circuit DC offset might be required. O Sensor gain selection: SW3 The integration amplifiers in the InGaAs linear image sensor have a function to select the integration capacitance (Cf). This selection is done by SW3 on the driver circuit. Switching SW3 to the left side selects the low gain, and switching it to the right side selects the high gain. The high gain is approx. 8 times higher than the low gain. Please note that the VIDEO signal from the driver circuit becomes saturated at approx. 4 V.
