TDA9885 TDA9885TS -- I2C-bus controlled single and multistandard alignment-free IF-PLL demodulators
Feature
5 V supply voltage
Gain controlled wideband Vision Intermediate Frequency (VIF) ampli?er, AC-coupled
Multistandard true synchronous demodulation with active carrier regeneration: very linear demodulation, good intermodulation ?gures, 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 I2C-bus
Digital acquisition help, VIF frequencies of 33.4 MHz, 33.9 MHz, 38.0 MHz, 38.9 MHz, 45.75 MHz and 58.75 MHz
4 MHz reference frequency input: signal from 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
Precise fully digital Automatic Frequency Control (AFC) detector with 4-bit digital-to-analog converter, AFC bits readable via I2C-bus
TakeOver Point (TOP) adjustable via I2C-bus or alternatively with potentiometer
Fully integrated sound carrier trap for 4.5 MHz, 5.5 MHz, 6.0 MHz and 6.5 MHz, controlled by FM-PLL oscillator
Sound IF (SIF) input for single reference Quasi Split Sound (QSS) mode, PLL controlled
SIF AGC for gain controlled SIF ampli?er, single reference QSS mixer able to operate in high performance single reference QSS mode and in intercarrier mode, switchable via I2C-bus
AM demodulator without extra reference circuit
Alignment-free selective FM-PLL demodulator with high linearity and low noise
