DATA SHEET
MOS INTEGRATED CIRCUIT
μ PD8882
(10680 + 10680) PIXELS × 3 COLOR CCD LINEAR IMAGE SENSOR
DESCRIPTION
The μ PD8882 is a color CCD (Charge Coupled Device) linear image sensor which changes optical images to
electrical signal and has the function of color separation.
The μ PD8882 has 3 rows of (10680 + 10680) staggered pixels, and each row has a dual-sided readout-type charge
transfer register. And it has reset feed-through level clamp circuits and voltage amplifiers. Therefore, it is suitable for
2400 dpi/A4 color image scanners.
FEATURES
• Valid photocell : (10680 + 10680) staggered pixels × 3
• Photocell’s size : 2.7 μ m × 5.4 μ m
• Line spacing
• Color filter
: 86.4 μ m (16 lines) Red line - Green line, Green line - Blue line
43.2 μ m (8 lines) Odd line - Even line (for each color)
: Primary colors (red, green and blue), pigment filter (with light resistance 107 lx•hour)
• Resolution
: 96 dot/mm A4 (210 × 297 mm) size (shorter side)
2400 dpi US letter (8.5” × 11”) size (shorter side)
• Drive clock level : CMOS output under 5 V operation
• Data rate
: Built-in amplifiers : 10.0 MHz Max. CCD transfer : 4.5 MHz Max./each CCD
• Power supply : +12 V
• On-chip circuits : Reset feed-through level clamp circuits
Voltage amplifiers
