ORDERING INFORMATION
1998 Jan 08
TDA9809M
TYPE NUMBER
5 V supply voltage
Applicable at Intermediate Frequencies (IFs) of 38.9 and
45.75 MHz
Gain controlled wideband 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 PLL bandwidth control for negative modulation
standards
VIF AGC (Automatic Gain Control) detector for gain
control, operating as peak sync detector for negative
modulation standards
Tuner AGC with adjustable TakeOver Point (TOP)
AFC (Automatic Frequency Control) detector without
extra reference circuit
AC-coupled limiting amplifier for sound intercarrier
signal
Alignment-free FM PLL (Phase-Locked Loop)
demodulator with high linearity; integrated de-emphasis
resistor
Integrated level detector
Alignment-free FM radio AFC detector with external
resonator
RIF (Radio IF) amplifier for 10.7 MHz
Stabilizer circuit for ripple rejection and to achieve
constant output signals
ESD (Electrostatic Discharge) protection for all pins.
Single standard multimedia IF-PLL and FM
radio demodulator
SSOP20 plastic shrink small outline package; 20 leads; body width 5.3 mm
