Analog RGB signal input The analog RGB signal must be input with 1.0 Vp-p or lower at a sufficiently low impedance. 2. Subcarrier input The subcarrier input to the MB3516A supports both of a sine wave from 1.0 to 5.0 Vp-p and a pulse. 3. Board pattern design The noise limiting capacitors to be inserted to the Vcc1 and Vcc2 pins must be connected to the GND1 and GND2 pins as closely to the pins as possible. The patterns to be connected to the GND1 and GND2 pins must be as wide as possible to reduce parasitic impedance. ■ ORDERING INFORMATION Part number MB3516APF Package Remarks 24-pin plastic SOP (FPT-24P-M01) 11 MB3516A ■ PACKAGE DIMENSION 24-pin plastic SOP (FPT-24P-M01) +0.25 2.25(.089)MAX (Mounting height) +.010 15.24 –0.20 .600 –.008 0.05(.002)MIN (STAND OFF) 5.30±0.30 (.209±.012) INDEX 0.45±0.10 (.018±.004) 1.27(.050) TYP +0.40 6.80 –0.20 7.80±0.40 (.307±.016) +.016 .268 –.008 +0.05 Ø0.13(.005) M 0.15 –0.02 +.002 .006 –.001 0.50±0.20 (.020±.008) Details of "A" part 0.20(.008) "A" 0.10(.004) 13.97(.550)REF 0.50(.020) 0.18(.007)MAX 0.68(.027)MAX Dimensions in mm (inches) C 12 1994 FUJITSU LIMITED F24007S-3C-4 MB3516A FUJITSU LIMITED For further information please contact: Japan FUJITSU LIMITED Corporate Global Business Support Division Electronic Devices KAWASAKI PLANT, 4-1-1, Kamikodanaka, Nakahara-ku, Kawasaki-shi, Kanagawa 211-8588, Japan Tel: +81-44-754-3763 Fax: +81-44-754-3329 http://www.fujitsu.co.jp/ North and South America FUJITSU MICROELECTRONICS, INC. 3545 North First Street, San Jose, CA 95134-1804, USA Tel: +1-408-922-9000 Fax: +1-408-922-9179 Customer Response Center Mon. - Fri.: 7 am - 5 pm (PST) Tel: +1-800-866-8608 Fax: +1-408-922-9179 http://www.fujitsumicro.com/ Europe FUJITSU MICROELECTRONICS EUROPE GmbH Am Siebenstein 6-10, D-63303 Dreieich-Buchschlag, Germany Tel: +49-6103-690-0 Fax: +49-6103-690-122 http://www.fujitsu-fme.com/ Asia Pacific FUJITSU MICROELECTRONICS ASIA PTE LTD #05-08, 151 Lorong Chuan, New Tech Park, Singapore 556741 Tel: +65-281-0770 Fax: +65-281-0220 http://www.fmap.com.sg/ F0003 FUJITSU LIMITED Printed in Japan All Rights Reserved.
