📥 Download Datasheet

Overview

Ordering number: EN 4037C Monolithic Linear IC LA7577N Super-split PLL-II VIF and SIF IF Signal Processor for TV/VTRs Overview The LA7577N is a high tone quality and high picture quality, video IF and sound IF IC.

It employs split processing of the video IF signal and sound IF signal using SAW filters and a PLL detector.

Further, the PLL detector incorporates a buzz canceler for Nyquist buzz interference suppression to achieve high tone quality.

Key Features

  • Employs split processing for wide bandwidth video characteristics.
  • PLL detector with buzz canceler for excellent buzz and buzz beat characteristics.
  • APC time constant switch built-in.
  • High-speed AGC supports double time constant method.
  • SIF carrier level AGC in the 1st SIF stage for good SIF weak electric field characteristics.
  • Good differential gain and phase characteristics.
  • RF AGC easily adjusted using a variable resistor Functio.
