LA75676VA
Monolithic Linear IC
IF Signal Processor (VIF+SIF)
for TV and VCR Products
Overview
The LA75676VA is a VIF/SIF IC that supports NTSC intercarrier reception and adopts a semi-adjustment-free design. It is
provided in the SSOP24 (225mil, 0.5mm lead pitch) package, which is appropriate for miniature 2-in-1 tuner products. In
the VIF block, it adopts a design that uses AFT adjustment to obviate the need for VCO adjustment, and thus can simplify
the adjustment steps required in end product manufacturing. It uses a PLL technique for FM detection. It features the 5V
supply voltage appropriate for multimedia products. In addition, it achieves superb audio quality by incorporating a buzz
canceller that suppresses Nyquist buzzing.
Functions
• VIF block: VIF amplifier, buzz canceller, PLL detector, IF AGC, RF AGC, AFT, and an equalizer amplifier
• SIF block: Limiter amplifier, PLL FM detector
