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.
Since the LA7565BM include an SIF converter on chip, it is easy to implement multi-system audio.
In addition, it also includes a buzz canceller that suppresses Nyquist buzz to achieve improved audio quality.
The LA7565G and LA7565KM feature improvements over the LA7565B and LA7565BM in the FM low-range frequency characteristics, vertical synchronization buzz, and AFT drift.
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 canceller • Equalizer amplifier • SIF converter • VIF amplifier • IF AGC [First SIF Block] • First SIF detector • First SIF amplifier [SIF Block] • PLL type FM detector • Limiter amplifier Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft’s control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage.
