TDA9808

INTEGRATED CIRCUITS DATA SHEET TDA9808 Single standard VIF-PLL with QSS-IF and FM-PLL demodulator Product specification Supersedes data of 1999 Jan 18 File under Integrated Circuits, IC02 1999 Jun 04 Philips Semiconductors Product specification Single standard VIF-PLL with QSS-IF and FM-PLL demodulator FEATURES 5 V supply voltage (9 V supply voltage for TDA9808 (DIP20) only) Applicable for IFs (Intermediate Frequencies) of 38.9 MHz, 45.75 MHz and 58.75 MHz Gain controlled wide band Video IF (VIF)-amplifier (AC-coupled) True synchronous demodulation with active carrier regeneration (very linear demodulation, good intermodulation figures, reduced harmonics, excellent pulse response) Robustness for over-modulation better than 105% due to Phase Locked Loop (PLL)-bandwidth control at negative modulated standards VIF Automatic Gain Control (AGC) detector for gain control, operating as peak sync detector Tuner AGC with adjustable TakeOver Point (TOP) Automatic Frequency Control (AFC) detector without extra reference circuit AC-coupled limiter amplifier for sound intercarrier signal Alignment-free FM-PLL demodulator with high linearity Sound IF (SIF) input for single reference Quasi Split Sound (QSS) mode (PLL controlled); SIF AGC detector for gain controlled SIF amplifier; single reference QSS mixer for high performance Electrostatic Discharge (ESD) protection for all pins.
