TDA9818 Product details

Description

TDA9817; TDA9818 AC-coupled limiter amplifier for sound intercarrier signal Alignment-free FM PLL (Phase Locked Loop) demodulator with high linearity SIF (Sound IF) input for single reference QSS (Quasi Split Sound) mode (PLL controlled); SIF AGC detector for gain controlled SIF amplifier; single reference QSS mixer able to operate in high performance single reference QSS mode and in intercarrier mode AM demodulator without extra reference circuit

Features

5 V supply voltage.
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 gated phase detector at L/L accent standard and PLL-bandwidth co.
