Technical content

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. n 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. ICs for VCR AN3497SB Chroma Noise Reduction IC 0.35–0.1 0.8 0.1–0.1 4.3–0.3 6.3–0.3 0.5 0.15 0.65 1.5–0.2 6.5–0.3 Unit : mm 16-Pin PANAFLAT Package (SSOP-016-P-0225a) 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 V CC GND EF 0dB A2 LPF Det.
