Overview

The LA7533 is an IC containing the VIF section and SIF section on a single chip in the DIP20 package. The use of the small-sized package serves to make VCR tuner units smaller.

As compared with the LA7530N, the LA7533 is improved in characteristics when it is operated at supply voltage 9V (DG, DP, RF AGC temperature characteristics). The LA7533 is applicable to the circuit designed for the LA7530N.

Features

• High-gain VIF amplifier requiring no preamplifier.

• Higher AGC speed.

• Adjustment-free FM detector because of ceramic discriminator-used quadrature detection.

• Possible to mute video, sound for VCR.

• Small-sized package.

• Minimum number of external parts required.

• Operated at supply voltage 9V.

Functions

• VIF section :VIF AMP, VIDEO DET, PEAK IF AGC, B/W NOISE CANCELLER, RF AGC, AFT, VIDEO MUTE.

• SIF section : SIF LIMITER AMP, FM DET, SND MUTE.
