Technical content

The AN5170K is a VIF/SIF signal processor IC for NTSC TVs and VCRs. The SIF part needs no coil and requires no adjustment. The AFT part needs no coil, and is adopted quasi-separate sound (QSS) method. n Features

  • The SIF part adopts PLL detection, needs no coil, and requires no adjustment.
  • The AFT part uses APC voltage, eliminating the need of a coil.
  • QSS technique is employed for better buzz characteris- tics and audio sensitivity.
  • EQ amplifier is used for video frequency-characteristics correction.
  • Low power consumption (5.0V, 48mA)
  • The AFT output circuit has its own power supply, VCC2 (from VCC1 to 12.5V), to be compatible with various types of tuners.
