Ordering number : ENN6803 Monolithic Linear IC LA7567GM TV and VCR VIF/SIF IF Signal-Processing Circuit with NTSC SPLIT Support Overview The LA7567GM is an NTSC SPLIT support VIF/SIF IF IC that adopts a semi-adjustment-free system. The VIF block adopts a technique that makes AFT adjustment unnecessary by adjusting the VCO, thus simplifying the adjustment steps in the manufacturing process. PLL detection is adopted in the FM detector. A 5-V powersupply voltage is used to match that used in mos.

Ordering number : ENN6803 Monolithic Linear IC LA7567GM TV and VCR VIF/SIF IF Signal-Processing Circuit with NTSC SPLIT Support Overview The LA7567GM is an NTSC SPLIT support VIF/SIF IF IC that adopts a semi-adjustment-free system. The VIF block adopts a technique that makes AFT adjustment unnecessary by adjusting the VCO, thus simplifying the adjustment steps in the manufacturing process. PLL detection is adopted in the FM detector. A 5-V powersupply voltage is used to match that used in most multimedia systems. In addition, this IC also includes a buzz canceller to suppress Nyquist buzz and provide high audio quality. Features • Both AFT and SIF inductors built in, thus making adjustment of external inductance unnecessary. • Built-in buzz canceller for excellent audio performance. • VCC = 5 V, low power dissipation (250 mW) Package Dimensions unit: mm 3112A-MFP24S [LA7567GM] 24 13 Functions [VIF] • VIF amplifier • PLL detector • BNC • RF AGC • EQ amplifier • AFT • IF AGC • Buzz canceller [First SIF] • First SIF • First SIF detector • AGC [SIF] • Multi-format SIF converter • Limiter amplifier • PLL FM detector 5.4 12.5 0.15 0.35 1.0 0.1 1.5 (0.75) SANYO: MFP24S Specifications Maximum Ratings at Ta = 25°C Parameter Maximum supply voltage Circuit voltage Symbol VCC max V13, V17 I6 Circuit current I10 I24 Allowable power dissipation Operating temperature Storage temperature Pd max Topr Tstg TA ≤ 50°C, Independent IC *: Mounted on a printed circuit board Conditions Ratings 6 VCC –3 –10 –2 420 720 –20 to +70 –55 to +150 Unit V V mA mA mA mW mW °C °C Note: When mounted on a 65 × 72 × 1.6 mm paper/phenolic resin printed circuit board.
