TDA9813T Description
plastic small outline package; body width 7.5 mm GENERAL DESCRIPTION TDA9813T The TDA9813T is an integrated circuit for vision IF signal processing and sound dual FM demodulation, with single reference QSS-IF in TV and VCR sets. For negative modulation standards only.
TDA9813T Key Features
- 5 V supply voltage
- Gain controlled wide band VIF amplifier (AC-coupled)
- True synchronous demodulation with active carrier regeneration (very linear demodulation, good intermodulation figures,
- Separate video amplifier for sound trap buffering with high video bandwidth
- VIF-AGC detector for gain control, operating as peak sync detector
- Tuner AGC with adjustable takeover point (TOP)
- AFC detector without extra reference circuit
- AC-coupled limiter amplifier for sound intercarrier signal
- Two alignment-free FM-PLL demodulators with high linearity
- SIF input for single reference QSS mode (PLL controlled); SIF-AGC detector for gain controlled SIF amplifier; single ref
