Transients under 0.0V in the clock pulses will lead to charge injection, causing a localized increase in the dark signal. If such spurious negative transients are present, they can be suppressed by inserting a serial resistor of appropriate value (typically 20 to 100Ω) in the corresponding driver output. Table 4.

VOS = average video output voltage. 2. Fs = 2 F ΦT. The minimum clock frequency is limited by the increase in dark signal. mA mA mA mW tRISE = 15 ns tRISE = 15 ns VINH = 0V VDD = 15V VINH = 0V VDD = 15V Electro-optical Performance General measurement conditions: TC = 25°C; Ti = 1 ms; FΦT = 2.5 MHz (FDATA = 5 MHz) Light source: tungsten filament lamp (2854 K) + B6 38 filter (2 mm thick), F/3.5 aperture. The filter limits the spectrum to 700 nm; in these conditions 1µJ/cm2 corresponds to 3.5 lux.s. Operating conditions (see Figure 1). First and last pixels, as well as reference elements, are excluded from the specification. Measurements taken on each output in succession. 1989A–IMAGE–05/02 5 5 Page Atmel Headquarters Corporate Headquarters 2325 Orchard Parkway San Jose, CA 95131 TEL 1(408) 441-0311 FAX 1(408) 487-2600 Europe Atmel Sarl Route des Arsenaux 41 Case Postale 80 CH-1705 Fribourg Switzerland TEL (41) 26-426-5555 FAX (41) 26-426-5500 Asia Room 1219 Chinachem Golden Plaza 77 Mody Road Tsimhatsui East Kowloon Hong Kong TEL (852) 2721-9778 FAX (852) 2722-1369 Japan 9F, Tonetsu Shinkawa Bldg. 1-24-8 Shinkawa Chuo-ku, Tokyo 104-0033 Japan TEL (81) 3-3523-3551 FAX (81) 3-3523-7581 Atmel Operations Memory 2325 Orchard Parkway San Jose, CA 95131 TEL 1(408) 441-0311 FAX 1(408) 436-4314 Microcontrollers 2325 Orchard Parkway San Jose, CA 95131 TEL 1(408) 441-0311 FAX 1(408) 436-4314 La Chantrerie BP 70602 44306 Nantes Cedex 3, France TEL (33) 2-40-18-18-18 FAX (33) 2-40-18-19-60 ASIC/ASSP/Smart Cards Zone Industrielle 13106 Rousset Cedex, France TEL (33) 4-42-53-60-00 FAX (33) 4-42-53-60-01 1150 East Cheyenne Mtn.
