2 / 32 page 1999 May 07 2 Philips Semiconductors Product specification Multistandard VIF-PLL with QSS-IF and AM demodulator TDA9810 FEATURES • 5 V supply voltage • Gain controlled wide band Video Intermediate Frequency (VIF)-amplifier (AC-coupled) • True synchronous demodulation with active carrier regeneration (very linear demodulation, good intermodulation figures, reduced harmonics, excellent pulse response) • Gated phase detector for L/L accent standard; robustness for over-modulation until 105% • Voltage Controlled Oscillator (VCO) frequency switchable between L and L accent (alignment external) picture carrier frequency • Separate video amplifier for sound trap buffering with high video bandwidth • VIF Automatic Gain Control (AGC) detector for gain control, operating as peak sync detector for B/G (optional external AGC) and peak white detector for L; signal controlled reaction time for L • Tuner AGC with adjustable TakeOver Point (TOP) • AFC detector without extra reference circuit • SIF-input for single reference Quasi Split Sound (QSS) mode (Phase Locked Loop (PLL) controlled); Sound Intermediate Frequency (SIF) AGC detector for gain controlled SIF amplifier; single reference QSS mixer able to operate in high performance single reference QSS mode • AM demodulator without extra reference circuit • AM mute (especially for NICAM) • Stabilizer circuit for ripple rejection and to achieve constant output signals. GENERAL DESCRIPTION The TDA9810 is an integrated circuit for multistandard vision IF signal processing and sound AM demodulation, with single reference QSS-IF in TV and VCR sets. ORDERING INFORMATION TYPE NUMBER PACKAGE NAME DESCRIPTION VERSION TDA9810 SDIP24 plastic shrink dual in-line package; 24 leads (400 mil) SOT234-1 TDA9810T SO24 plastic small outline package; 24 leads; body width 7.5 mm SOT137-1 |
