No, 1852 LC7410,7411,7415 a p> © MOS LSI 4 F SANYO VTR (G/VHS} SERVO CIRCUIT The LC7410, 7411, 7415 are digital controller CMOS LSI's for VTR (8/VHS) saxo cicgiilt' use. Since gy” servo characteristics can be achieved by coding the on-chip mask ROM’s and extornally dddressing the'ROM's, Wey can be applied to any multifunctional VTR’s. The C7410, 7411, 7415 can be used in conjunction withnterfagd JC LA7110 to form a servo system with a good cost performance. ff a ae Features ff er ff © Speed/phase control of drum unit if a, _ éé ® Speed/phase control of capstan unit (For speed control, mask optién’permits:2EG Bhiitication aso.) © Color subcarrier signal (fg) is programmable-divided to generate internal referente signal (REF30), ® Tape speed (recording time mode) detection (GI/GU/SI2, SP/LP/EP) ame Ned? fe © Control signa! phasing capability during edit recording if € » a ; of © Mode (PB, REC, special PB, etc.) selection (max. 16 modes}.is made b¥4-bit binary data. © A wide variety of stepwise search (1/2, 1, 2, 3, 4,5, ov Yomax yy “Yb of © Destination (NTSC/PAL) is pin-selectable. if sé fe @ The on-chip input amp acts to permit color subcarrier: ‘signal (V1 N20.38Vp.p) t0,b¢ interfaced. © Operating voltage (Vpp=4.5 to 5.5V)/operating eustent dissipation (Ipp tyb,#3mA) © Operating temperature (Tg=-30 to +70°C) ff vd @ Package: DIP30 (LC7410-XX), DIP42S (LC74M-Xx)s6r CIPAg t N{L.C7415/XX) Lc7410 ff ew fy fae Outline 3051 oe _ ep if x” of fe AUDO ROL RANA ar Arar HS Case Outline 3052A-O48AIC ae in us rr ee re 2.0 a Co¥o Outling 30258-Dazsic. | PAPER ADs * SSS rosso th = E= i oS oF ct = — SES at BNO eenee 7 Ty ik aie ANCUOBGUUTNY SANYO: DIP42S SANYO: QIP48A 2as These specifications are subject to change without notice.
