General 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 con
Key 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.
