TDA9801中文资料Single standard VIF-PLL demodulator and FM-PLL detector数据手册恩XP规格书

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
