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.
Functions
[VIF]
• VIF amplifier • PLL detector • BNC • RF AGC
• EQ amplifier • AFT
• IF AGC • Buzz canceller
[SIF]
• Limiter amplifier • PLL FM detector
Features
• No AFT or SIF coils are used, thus eliminating
adjustments.
• Excellent audio performance due to the built-in buzz
canceller.
• V_CC = 5 V and a low power dissipation of 250 mW.
