  • Light weight General Description The PI330MC-DR is a contact image sensor, CIS, module with a n additional on board circuit that digitizes the analog pixels from the CIS image sensor to a “ background- tracking ” , two-level digital output signals. It is based on CIS modu le, the PI305M-A6 manufactured by PIC, but with a shorter read length of 89 mm . Hence, its performance is equivalent to the PI305M-A6 that uses MOS image sensor technology to gains its high- speed performance and high sensitivity. The PI330MC-DR is su itable for scanning documents with width of 89 mm and with resolution of 11.8 do ts per millimeter. Its has a broad applications, but specially designed for the following areas:
  • Where data compression is required, such as in data transmis sions.
  • Where component pin-out count must be kept to a minimum. PI330MC-DR 300DPI CIS Two Level Digital Output Module Engineering Data Sheet Peripheral Imaging Corporation PAGE 1 OF 9 - PI330MC-DR, 4/13/00

Table 1. Pin configuration The connector is a 8-pin 1-mm surface mount flex input, Molex 52207-0890.

  • Clock is on Pin 6 of the I/O Connector. This is main clock i nput into the CIS Module.
  • SP is on Pin 4. This is the start clock input to the CIS Mo dule. PAGE 4 OF 9 - PI330MC-DR, 4/13/00
  • VDD is on Pin 2. This is a + 5 Volts supply.
  • VN is on Pin 3. This is a ( – 10 to – 5) Volts supply.
  • VLED is on Pin 8. This is a +24 Volts supply for the LED lig ht source. Note: Power return for the LED light source is GLED on Pin 7 and the ground return for the CIS modules is pin 5. Video Output : DIGOUT is on pin 1 of the I/O connector. This is the digital video output from the CIS module. Reflection off the dark target produces a digital si gnal of “ 0 ” level, while the white reflection off the white target produces a digital level of “ one ” . The amplitudes of the white and dark are listed in the table below: Electro-Optical Characteristics (25 ° C)
