and FM-PLL detector

Product specification

TDA9801

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 a monolithic integrated circuit for vision

and sound IF signal processing in TV and VTR sets and

multimedia front-ends.
