tv and vcr vif/sif if signal-processing circuit.
* Both AFT and SIF inductors built in, thus making adjustment of external inductance unnecessary.
* A PAL/NTSC multi-format audio system can be constructed easily.
Pin No. Pin Description Equivalent circuit
1
SIF INPUT
* SIF input. The input impedance is about 1 kΩ. Since buzzing and buzz beating can occur if interference enters this input pin, care must be taken when design the pattern layout for this .
