Description:

If signal-processing ic.

LA75691, IF Signal-Processing IC

Pin No.

Pin Function Equivalent circuit SIF input The input impedance is about 1 kΩ.

The pattern layout for the input circuit for this pin must be designed carefully, since buzzing and/or beating can be caused by interference signals.

Video signals, the chrominance signal, and the VIF carrier sign

Ordering number : EN5734 Monolithic Linear IC LA75691 IF Signal-Processing IC for PAL/NTSC Multichannel Audio TV and VCR Systems Overview The LA75691 is a PAL/NTSC multichannel audio VIF/SIF signal-processing IC that makes the minimum number of adjustments possible.

The system is designed so that VCO adjustment makes AFT adjustment unnecessary, thus simplifying the adjustment steps in endproduct manufacturing.

PLL detection is adopted in the FM detector, allowing the LA75691 to support multic

LA75691 Features

* Excellent buzz and buzz/beating characteristics provided by a PLL detection technique that includes a buzz canceller.

* The second IF AGC filter is built in.

* No coils are used in the AFT and SIF circuits, making them adjustment free. Allowable power dissipation, Pd max
