LA75675M-S
VIF/SIF IF Signal-Processing Circuit that Supports
NTSC Intercarrier for TV and VCR Products
Overview
The LA75675M-S is an NTSC intercarrier VIF/SIF IC
that adopts a semi-adjustment-free structure. In particular,
it uses VCO adjustment to make AFT adjustment
unnecessary and thus simplifies the overall adjustment
process. A PLL-based technique is adopted for FM
detection. The 5 V supply voltage provides compatibility
with other multimedia systems. In addition it achieves
high audio quality by incorporating a built-in buzz
canceller that suppresses Nyquist buzz.
Features
鈥?No AFT or SIF coils are used, thus eliminating
adjustments.
鈥?Excellent audio performance due to the built-in buzz
canceller.
