LA7567NM - TV and VCR VIF/SIF IF Signal-Processing Circuit

Datasheet Summary

Description

Pin No.

SIF input.

The input impedance is about 1 kΩ.

Since buzzing and buzz beating can occur if interference enters this input pin, care must be taken when design the pattern layout for this pin.

Features

Both AFT and SIF inductors built in, thus making adjustment of external inductance unnecessary.
A PAL/NTSC multi-format audio system can be constructed easily.
Built-in buzz canceller for excellent audio performance.
VCC = 5 V, low power dissipation (250 mW) 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 Storag.

Ordering number : EN5765 Monolithic Linear IC LA7567N, 7567NM TV and VCR VIF/SIF IF Signal-Processing Circuit with PAL/NTSC Multi-Format Audio Support Overview The LA7567N and LA7567NM are PAL/NTSC multiformat audio VIF/SIF IF ICs that adopt a semiadjustment-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 to support multi-format audio detection. A built-in SIF converter is included to simplify multi-format system designs. A 5-V power-supply voltage is used to match that used in most multimedia systems. In addition, these ICs also include a buzz canceller to suppress Nyquist buzz and provide high audio quality.
