Description
UTC7607/7611
The UTC7607/7611 is a monolithic integrated circuit designed for the VIF stage in color and B/W television receivers. The UTC7607 is used for Reverse AGC Type. The UTC7611 is used for Forward AGC Type.
LINEAR INTEGRATED CIRCUIT
*Three controlled IF amplifier stages *Video demodulator controlled by picture carrier *Black noise and white noise inverter *Peak AGC *DC amplifier for RF AGC output *Quadrature detector for AFT *DC amplifier for AFT
DIP-16
*High gain wide brand IF amplifier *Gain reduction with excellent stability *Excellent DG/DP and S/N characteristics
*Negative video output signal *Fast AGC action due to noise inverter and peak AGC *Switch off the video part VTR S
