AN5138NK
Video IF Amplifier, PLL Detector, AGC, AFC, SIF IC for Color TV
s Overview
The AN5138NK is an integrated circuit designed for
video-IF and audio-IF processing circuits, in color TV and
VCR.
s Features
• By adopting built-in VCO PLL-type video-detector cir-
cuit, the high preformance IC-detector system can be
realized for sound multiplex and tele-text broadcasting.
• Quadrature sound FM detector built-in.
• Frequency characteristics compensation pin (Pin20)
VCR-switch pin (Pin5)
• Sound-output level-adjustment pin (Pin25)
