Product Summary
The TDA9802 is a monolithic integrated circuit for vision and sound IF signal processing in multistandard TV and VTR sets.
Parametrics
TDA9802 absolute maximu mrating: (1)supply voltage: 8.8 V; (2)VI voltage on pins 1, 2, 7, 8, 11, 13, 14, 15 and 19: VP V; (3)ts max short-circuit time: 10 s; (4)V12 tuner AGC output voltage: 13.2 V; (5)Tstg storage temperature range: -25 +150 ℃; (6)VESD electrostatic handling for all pins (note 2): ±300 V.
Features
TDA9802 features: (1)Suitable for negative and positive vision modulation; (2)Gain controlled 3-stage IF amplifier; suitable for VIF frequencies up to 60 MHz; (3)True synchronous demodulation with active carrier regeneration (ultra-linear demodulation, good intermodulation figures, reduced harmonics and excellent pulse response); (4)Peak sync AGC for negative modulation, e.g. B/G standard; (5)Peak white AGC for positive modulation, e.g. L standard; (6)Video amplifier to match sound trap and sound filter; (7)AGC output voltage for tuner; adjustable take-over point(TOP); (8)AFC detector without extra reference circuit; (9)Alignment-free FM-PLL detector with high linearity; (10)Stabilizer circuit for ripple rejection and to achieve constant output signals; (11)5 to 8 V positive supply voltage range, low power consumption (300 mW at +5 V supply voltage).
