LA7578N Product details

Overview

The LA7578N is an intercarrier-type VIF + SIF IC that supports excellent sound quality and image quality. The pin assignment of the LA7578N is identical to that of the LA7577N, allowing the LA7577N to be used for split systems while the LA7578N is used for intercarrier systems. In addition, the LA7578N suppresses Nyquist buzz interference by using a PLL detection system with a buzz canceller in order to provide the best sound quality possible.



Features

. Excellent buzz and buzz-beat characteristics due to PLL detection system with buzz canceller.

. Built-in APC time constant switch.

. Duplicate time constant system suited for high-speed AGC.

. Excellent DG and DP characteristics.

. RF AGC adjustment is simple.
