Monolithic Linear IC

LA7449, 7449M

Video Signal Processing IC

for VHS VCR Systems

Overview

The LA7449 and 7449M are video signal processing singlechip ICs that handle the PAL-G, B and I, 4.43 NTSC, MESECAM and NAP-G, B and I formats. IC internal trimming is used to make the LA7449, 7449M completely adjustment free, and in combination with a special-purpose CCD (thd LC89970, 89970M) they provide a significant reduction in external components, including the glass delay line. Thus the LA7449, 7449M can significantly reduce the signal processing board manufacturing costs. Furthermore, the LA7449, 7449M support the NAP format (NTSC to PAL conversion) that is becoming widespread in

Europe, China and other markets.

Features

•Completely adjustment free.

The AGC, carrier, deviation, and PB-Y level are adjustment free.

The YC record current can also be made adjustment free by using the LA7411, 7416 as the head amplifier.

•Support for NAP and PAL color array correction.

Full modulation using a balanced modulator allows playback and conversion to PAL format of NTSC signals recorded on tape.

•Crosstalk exclusion in combination with a special-pur- pose CCD

Crosstalk can be excluded without using a glass delay line by combining the LA7449, 7449M with a specialpurpose CCD (the LC89970, 89970M).

•Minimal number of external components. New built-in components :

–Detail enhancer CR.

–C-trap in the Y low-pass filter.

–Playback C low-pass filter.

•High performance and multiple functions. Linear phase picture controller.

Double high-pass noise canceller, high-speed AFC, DCC. New built-in functions.

–NAP circuit.

–AVNS (advanced vertical noise suppressor).

–Automatic QH insertion.

–FM AGC.

•Miniature package (48-pin QIP or DIP).
