Product Details

Description



Features:

5V supply voltage (9V supply voltage for TDA9808(DIP20) only)
Applicable for IFs (Intermediate Frequencies) of
38.9MHz, 45.75MHz and 58.75MHz
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 (PLLcontrolled); SIF AGC detector
for gain controlled SIF amplifier; single reference QSS mixer for high performance
Electrostatic Discharge (ESD) protection for all pins.
