描述 Description

GENERAL DESCRIPTION
The TDA9801(T) is a monolithic integrated circuit for vision and sound IF signal processing in TV and VTR sets and multimedia front-ends.FEATURES
? Suitable for negative vision modulation
? Applicable for IF frequencies of 38.9, 45.75 and 58.75 MHz
? Gain controlled wide-band Vision Intermediate Frequency (VIF) amplifier (AC-coupled)
? True synchronous demodulation with active carrier regeneration (ultra-linear demodulation, good intermodulation figures, reduced harmonics and excellent pulse response)
? Peak sync pulse AGC
? Video amplifier to match sound trap and sound filter
? AGC output voltage for tuner with fixed resistor for takeover point setting
? AFC detector without extra reference circuit
? Alignment-free FM-PLL detector with high linearity
