TDA9886TS

 

 

 

FEATURES

• 5 V supply voltage

• Gain controlled wide-band Vision Intermediate

Frequency (VIF) amplifier, AC-coupled

• Multistandard true synchronous demodulation with

active carrier regeneration: very linear demodulation,

good intermodulation figures, reduced harmonics, and

excellent pulse response

• Gated phase detector for L and L-accent standard

• Fully integrated VIF Voltage Controlled Oscillator

(VCO), alignment-free, frequencies switchable for all

negative and positive modulated standards via I2

C-bus

• Digital acquisition help, VIF frequencies of 33.4, 33.9,

38.0, 38.9, 45.75, and 58.75 MHz

• 4 MHz reference frequency input: signal from

Phase-Locked Loop (PLL) tuning system or operating

as crystal oscillator

• VIF Automatic Gain Control (AGC) detector for gain

control, operating as peak sync detector for negative

modulated signals and as a peak white detector for

positive modulated signals

• External AGC setting via pin OP1

• Precise fully digital Automatic Frequency Control (AFC)

detector with 4-bit digital-to-analog converter, AFC bits

readable via I2

C-bus

• TakeOver Point (TOP) adjustable via I2

C-bus or

alternatively with potentiometer

• Fully integrated sound carrier trap for 4.5, 5.5,

6.0, and 6.5 MHz, controlled by FM-PLL oscillator

• Sound IF (SIF) input for single reference Quasi Split

Sound (QSS) mode, PLL controlled
