Overview

INTEGRATED CIRCUITS DATA SHEET TDA9806 Multistandard VIF-PLL and FM-PLL demodulator Preliminary speciﬁcation File under Integrated Circuits, IC02 1995 Sep 05 Philips Semiconductors Preliminary speciﬁcation Multistandard VIF-PLL and FM-PLL demodulator FEATURES • 5 V supply voltage • Gain controlled wide band VIF-amplifier (AC-coupled) • True synchronous demodulation with active carrier regeneration (very linear demodulation, good intermodulation figures, reduced harmonics, excellent pulse response) • Separate video amplifier for sound trap buffering with high video bandwidth • VIF AGC detector for gain control, operating as peak sync detector for B/G • Tuner AGC with adjustable takeover point (TOP) • AFC detector without extra reference circuit • AC-coupled limiter amplifier for sound intercarrier signal • Alignment-free FM-PLL demodulator with high linearity, switchable de-emphasis for FM • Stabilizer circuit for ripple rejection and to achieve constant output signals.
