AI1002

Ver1.0 1 A1 PROs A1 PROs GENERAL DESCRIPTION Ai1002 Vertical Clock Driver for Camera System 20-pin SSOP The Ai1002 is a vertical driver for CCD image sensors. This IC is the successor of the Ai1001S with better features. 3.3V and 5V clock interface is acceptable while Ai1001S can accept only 5V clock interface. #1 FEATURES • • • Only two power supplies are ( +15V and -8.5V) needed. 3.3V and 5V clock interface is acceptable. 20-pin SSOP package APPLICATIONS CCD Cameras PROCESS High Voltage CMOS BLOCK DIAGRAM GND XSUB XV2 XV1 XSG1 XV3 XSG2 XV4 VCP DCIN 1 2 3 4 5 6 7 8 9 10 + 20 19 18 17 16 15 14 13 12 11 VP1 (+15V) VSUB VSS (−8.5V) VΦ2 VΦ1 VP0 (0V) VΦ3 VΦ4 VP1(+15V) DCOUT 1 Ai1002 PIN DESCRIPTION Pin 1 2 3 4 5 6 7 8 9 10 11 12 13 Symbol GND XSUB XV2 XV1 XSG1 XV3 XSG2 XV4 VCP DCIN DCOUT VP1 VΦ4 I/O I I I I I I I I I O O Ground Control Output Control (VSUB) Output Control (VΦ2) Output Control (VΦ1) Output Control (VΦ1) Output Control (VΦ3) Output Control (VΦ3) Output Control (VΦ4) Power of Amp OP-Amp Input (internal pull-down resistor) OP-Amp Output Power (15V) High Voltage Output (2 level : VP0, VSS) High Voltage Output (3 level : VP0, VSS, VP1) Power (0V) High Voltage Output (3 level : VP0, VSS, VP1) High Voltage Output (2 level : VP0, VSS) Power (− 8.5V) High Voltage Output (2 level : VSS, VP1) Power (15V) Description 14 VΦ3 O 15 VP0 - 16 VΦ1 O 17 18 19 20 VΦ2 VSS VSUB VP1 O O - 2 Ai1002 ABSOLUTE MAXIMUM RATINGS ( Ta = 25°C ) Characteristics Symbol VSS Supply Voltage VP1 VP0 VI Input Voltage VCP Output Voltage OP-Amp Output Current Operating Temperature Storage Temperature VΦ1, VΦ2, VΦ3, VΦ4, VSUB IOUT TOPR TSTG − 0.3 ~ VSS + 35 VSS − 0.3 ~ VP1 + 0.3 ±5 − 25 ~ + 85 °C − 45 ~ + 120 mA Value 0 ~ −10 −0.3 ~ VSS + 35 VSS − 0.3 ~ 3.0 − 0.3 ~ VP1 + 0.3 V Unit LOGIC FUNCTION TABLE INPUT XV1,3 L H L H X X X X X : Don’t care Z : High impedance XSG1,2 L L H H X X X X XV2,4 X X X X L H X X XSUB X X X X X X L H VΦ1,3 VP1 Z VP0 VSS X X X X OUTPUT VΦ2,4 X X X X VP0 VSS X X VSUB X X X X X X VP1 VSS 3 Ai1002 AC CHARACTERISTICS ( VP1 = 15V, VP0 = GND, VSS = -8.5V ; Ta = 25°C ) Description Symbol TPLM TPMH TPLH Delay Time TPML TPHM TPHL TTLM TTMH TTLH Rising Time TTML TTHM TTHL Output Noise Voltage VCLH, VCLL VCMH, VCML VP0 → VSS (*1) VP1 → VP0 (*1) VP1 → VP0 (*1) (*2) 200 400 10 300 600 50 500 820 100 0.5 V No Load(*1) No Load(*1) No Load(*1) VSS → VP0 (*1) VP0 → VP1 (*1) VSS → VP1 (*1) 10 10 10 400 400 10 100 100 60 700 650 50 200 180 100 ns 930 930 100 Test Condition No Load (*1) No Load(*1) No Load(*1) Min 10 10 10 Typ 40 30 40 Max 70 70 100 Unit (*1) Refer the timing diagram of page 5.
