andNT/PALSW

DESCRIPTION

signal,with

PLL system and no abjustment.

The N52766FP correspond to PLL split system and

intercareer system. AFT coil is necessary. AFT mute is not used. The M52766FP optimum for VTR and color TV,with video

output-pin,because this IC has a built in EQ amplifier. VCC correspond to 5V,be main strem of tuner in future. Flat package is 24-pin SSOP of mini flat (0.8mm pich ),

suitable for space saving.

The M52766FP is a semiconducttor IC with PLL system of

VIF/ SIF.

The circuit includes video UF amplifier,PLL video detector,IFAGC,RFAGC,VCO,AFT,LOCK DET,EQ,REG,QIFamplifier,QIF detector,QIF AGC,LIM,FM detector function.

The circuit realize no abjustment SIF,nothing coil AFT.

FEATURES

Dynamic AGC realizes high speed AGC with double filtre. The M52766FP can correspond to 2tipe sound career,from

change on standard board,with sound LIM input have 2pins (12,13pin).

Sound FM detection can correspond to wide SIF
