Overview
The AN3497SB is a chroma noise reduction (CNR) IC
for VCR and uses a chroma recursive filter system. In
combination with the AN2260 (luminance signal process-
ing), AN2460 (chroma signal processing), etc., it config-
ures a VHS signal processing system.

Features
Capable of meeting with the NTSC/PAL system.
Capable of meeting with the EDIT mode and THRU
mode.
The CNR limiter level and CNR output level can be adjust-
ed depending on external DC.
The feedback constant (KC) can be set optionally depend-
ing on an external resistor.
The chroma signal can be adjusted depending on an
external resistor.
Built-in functions such as Y vertical correlative signal
detector, etc.
