TDA9801 Datasheet PDF - Philips

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
