AMIS-710650-A6: Color CIS Module Data Sheet Analog Video Output 1.0 Description The AMIS-710650-A6 (PI650MC-A6C) is a color contact image sensor (CIS) module. The module contains seven image sensor chips, AMIS-720058 (PI6058H), a product of AMI Semiconductor. These chips are sequentially cascaded to provide a line array of photodetectors. Each photo-detector in the image sensor possesses its own independent processing circuit. As the photo-sensors’ digital shift register scans the image sensor chip, it sequentially produces the video signals at the output of the image array. The AMIS710650-A6’s mechanical outline drawing is shown in Figure 6. 2.0 Key Features • • • • • • • • • • 600 and 300dpi selectable resolutions 23.6dpm and 11.8dpm, 102mm scanning length 344 or 172 image sensor elements (pixels) Low power-single power supply at 3.3V Light source, lens and sensor are integrated into a single module High speed page scan - up to 602µsec/line @ 4MHz pixel rate Analog output RGB color LED light source Compact size ≅ 12.3mm x 18.9mm x 125mm Light weight 3.0 Overview The AMIS-710650-A6 has a 102mm read width. Its minimum line rate is 602us/line with a maximum clock pulse (CP) equal to 4.0MHz (pixel rate (PRATE), of 4.0MHz). Unless stated otherwise, all data was taken with CP = 3.0MHz (PRATE = 3.0MHz) and an integration time of 685us/line. The sensor photo-site density is 23.64elements/mm. The module has one analog video output, two clock inputs, clock and start pulse (CP and SP), one reference voltage input for the amplifier output bias level control, one power supply input and four LED inputs. 4.0 Scan Overview Table 1 describes a scan overview.

The reduction in the exposure proportionately reduces the video output. Accordingly, the signal-to-noise ratio reduces as the frequency increased.

This signal pixel level should be operated at less than saturation levels, i.e., <1.3V. VREF is used to adjust the video output bias. Under normal operation it is left unconnected. FREQ is the input clock (CP) frequency and the pixel rate (PRATE). The minimum rate for FREQ and PRATE should be consistent with the maximum TINT, see Note 5. DUTY is the ratio of the clock’s pulse width to its pulse period. TINT is the time interval between two start pulses (SP). Hence, if SP is generated from a clock count down circuit, it will be directly proportional to the clock frequency. There must be a minimum of (56+1204) clock cycles between the two SPs. The longest integration time is determined by the degree of leakage current degradation that can be tolerated by the system. A 10ms maximum is a typical rule-of-thumb. An experienced CIS user can use his discretion to determine the desired leakage tolerance level for the given system. TOP is a conservative engineering estimate. It is based on measurements of similar CIS modules. In production, they are measured under standard QA practices, that is, under the control of ISO 9000 standards.

See Table 3, Note 5. Clock frequency, FREQ, is the input clock frequency and its corresponding PRATE is the pixel sample rate. Bright output voltage Vpmax = maximum pixel value of Vp(n), Vpmin = minimum pixel value of Vp(n), Vpavg = ∑ Vp(n)/2408; where Vp(n) is the nth pixel in a line scan with the module scanning a uniform white target and Vp values are measured with a uniform exposure. (4) Bright output non-uniformity Up(+) = [(Vpmax - Vpavg) / Vpavg] x 100%, Up(-)= [(Vpavg - Vpmin) / Vpavg] x 100%, whichever polarity with the highest absolute value is selected. (5) Bright output total non-uniformity: Uptotal = [Vpmax -Vpmin]/Vpavg x 100% (6) Adjacent pixel non-uniformity: Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n))] x 100% Upadj is the non-uniformity in percentage. It is the maximum difference amplitude between two neighboring pixels. (7) Dark non-uniformity: Ud = Vdmax – Vdmin Vdmax is the max. pixel value of the video pixel in the dark. Vdmin is the min. pixel value of the video pixel in the dark. The references for these levels are the dark level (VDL). (8) Dark output voltage range (VDL) is the level between the output dark level and ground. (9) Random noise (RNL): The rms value was calculated from measured p-p thermal noise taken at output from a selected pixel. The rms is defined as one standard deviation of at least 64 pixels sampled. The calculation of the standard deviation is based on an idealized Gaussian probability curve. (10) Modulation transfer function is defined as MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100%. MTF is a measure at the glass surface. Vmax is the maximum output voltage at 300lp/inch (at 1/2 of the optical Nyquest frequency) and Vmin is the minimum output voltage at 300lp/inch. 8.0 Electrical Clocking Characteristics ° Table 5: Clock Amplitude Duty Characteristics (25 C) Parameter Symbol (1) Clock input voltage VIH (1) VIL (2) Clock frequency FREQ (2) Pixel rate PRATE (4) Line read time TINT (5) Clock pulse duty cycle Ratio = twp / tp Notes: (1) (2) (3) (4) (5) Min.

FREQ is the clock frequency and PRATE is the pixel sample rate. Minimum values are not specified because it will be determined by the maximum TINT value. See Note 4. TINT is the line scan read time, which depends on the interval between the SP entries. The minimum time is determined by (1/clock frequency) x (2408 + 150) pixels. Note that there are a few extra pixels used to determine the typical line time of 820µsec @ 3.0MHz PRATE (see Section 9.0). There are 55 clocks required to transfer and reset the photo-sites before the video can be scanned out. The longest integration time is determined by the degree of leakage current degradation that can be tolerated by the system. A 10ms maximum is a typical rule-of-thumb. An experienced CIS user can use his discretion and determine the desired tolerance level for the given system. The definition for the symbols used in the ratio is defined in Table 6. A duty cycle of exactly 50 percent is recommended to maintain equal pixel duration between odd and even pixels.
