Product Details

Description



Features:

5V supply voltage
Applicable at Intermediate Frequencies (IFs) of 38.9 and 45.75MHz
Gain controlled wideband Video IF (VIF) amplifier (AC-coupled)
True synchronous demodulation with active carrier
regeneration (very linear demodulation, good
intermodulation figures, reduced harmonics,
excellentpulse 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 FMradio AFC detector with external resonator
RIF (Radio IF) amplifier for10.7MHz
Stabilizer circuit for ripple rejection and to achieve
constant output signals
ESD (Electrostatic Discharge) protection for all pins.
