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.
