IF Signal Processing Circuit (A2C PLL VIF SIF) for TVs and VCRs

Overview The LA7583 is a VIF + SIF IC that requires no adjustments. In order to eliminate the need for adjustments in the VIF block, a multi-network PLL has been developed and adopted for video detection. In the SIF block, adjustments were eliminated by using gyrator technology in the FM quadratu
