2 / 40 page 1998 Jul 14 2 Philips Semiconductors Product specification Multistandard vision and sound-IF PLL with DVB-IF processing TDA9819 FEATURES • 5 V supply voltage • Applicable for IF frequencies of 38.9 MHz and 45.75 MHz • Two switched VIF inputs, gain controlled wide band VIF-amplifier (AC-coupled) • True synchronous demodulation with active carrier regeneration (very linear demodulation, good intermodulation figures, reduced harmonics and excellent pulse response) • VCO frequency switchable between TV (M or BG/L) IF-picture carrier and Digital Video Broadcast (DVB) frequency • Separate video amplifier for sound trap buffering with high video bandwidth • VIF AGC detector for gain control, operating as peak sync detector for M and B/G and peak white detector for L; controlled reaction time for L • Tuner AGC with adjustable takeover point (TOP) • AFC detector without extra reference circuit • SIF input for single reference QSS mode (PLL controlled); SIF AGC detector for gain controlled SIF amplifier; single reference QSS mixer able to operate in high performance single reference QSS mode • AC-coupled limiter amplifier for sound intercarrier signal • Alignment-free FM-PLL demodulator with high linearity • AM demodulator without extra reference circuit • Stabilizer circuit for ripple rejection and to achieve constant output signals. DVB functions • Gain controlled IF-amplifier • Mixer for DVB-IF • VCO for QAM carrier recovery • External VCO control for DVB • Internal and external AGC for DVB • DVB output level adjust via AGC adjust • High level DVB operational output amplifier. GENERAL DESCRIPTION The TDA9819 is an integrated circuit for multistandard vision and sound-IF signal processing with single reference PLL demodulator combined with the signal stages for DVB-IF processing. ORDERING INFORMATION TYPE NUMBER PACKAGE NAME DESCRIPTION VERSION TDA9819 SDIP32 plastic shrink dual in-line package; 32 leads (400 mil) SOT232-1 TDA9819T SO32 plastic small outline package; 32 leads; body width 7.5 mm SOT287-1 |
