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
• Stabilizer circuit for ripple rejection and to achieve
constant output signals
• 5 to 9 V positive supply voltage range
• Low power consumption of 300 mW at 5 V supply
voltage.
GENERAL DESCRIPTION
The TDA9801(T) is amonolithic integrated circuit for vision
and sound IF signal processing in TV and VTR sets and
multimedia front-ends.
