Overview

www.DataSheet4U.com Ordering number :ENN6100A Monolithic Linear IC LA7565E, 7565KM IF Signal-Processing IC for PAL/NTSC Multi-System Audio TV and VCR Products Overview The LA7565E and LA7565KM are PAL/NTSC multisystem audio VIF/SIF signal-processing ICs that adopt a minimal-adjustment technique.

The VIF circuit adopts a minimal-adjustment technique in which AFT adjustment is made unnecessary by VCO adjustment to simply end product adjustment.

The FM detector circuit uses PLL detections to support multi-system audio detection.

Key Features

  • Allows the use of a switch circuit to switch between spilt and intercarrier operation.
  • Improved buzz and buzz beat characteristics provided by a PLL detector plus buzz canceller system.
  • The IF AGC second filter is built in.
  • PAL/NTSC multi-system audio can be implemented easily.
  • Adjustment-free circuit design that does not require AFT and SIF coils. Functions [VIF Block].
  • PLL detector.
  • AFT.
  • RF AGC.
  • Buzz cancell.
