AN3501NFBP

Luminance, chroma and linear audio signal processing IC for VCR

■ Overview

The AN3501NFBP is a luminance, chroma signal
processing IC for VCR (PAL and NTSC). It also inte­grates a playback equalizer and an NTSC playback cir-

64

cuit.

A normal audio signal recording/playback circuit is
added so as to design a signal processing PCB in common
for both a HiFi and a normal model, resulting in space
saving of equipment.

This IC is a completely adjustment-free device which

84

has been realized by introducing a adjustment-free tech­nology such as a Zener zap, and contributes to a more
efficient design/development and production of an equip­ment.

■ Features

• Supply voltage range 4.8 V to 5.2 V (600 mW typ.)

• Usable for 4.43 MHz/3.58 MHz systems

• 4.43 MHz system: PAL/NTSC/ME-SECAM

• 3.58 MHz system: NTSC/PAL-N

• Adjustment-free

• Video output level (recording mode)

• Video output level (playback mode)

• White clip level

•f

frequency: sync. tip frequency

O

• FM deviation

• FM level (recording mode)

• Chroma level (recording mode)

• Normal audio circuit built in

• NTSC to PAL conversion by adopting a simplified NTSC playback circuit of a line skip method.

• ME-SECAM discrimination circuit built-in

• All filters built-in, including a CCD filter

• The upper part flicker suppression by adoption of an ACC circuit by the field and an adaptive APC circuit
