General description

The TDA9885 is an alignment-free multistandard (PAL and NTSC) vision and sound

IF signal Phase-Locked Loop (PLL) demodulator for negative modulation only and

FM processing.

The TDA9886 is an alignment-free multistandard (PAL, SECAM and NTSC) vision and

sound IF signal PLL demodulator for positive and negative modulation, including sound

AM and FM processing.

Features

I 5 V supply voltage

I Gain controlled wideband Vision Intermediate Frequency (VIF) ampliﬁer, AC-coupled

I Multistandard true synchronous demodulation with active carrier regeneration: very

linear demodulation, good intermodulation ﬁgures, reduced harmonics, and excellent

pulse response

I Gated phase detector for L and L-accent standard

I Fully integrated VIF Voltage-Controlled Oscillator (VCO), alignment-free, frequencies

switchable for all negative and positive modulated standards via I2C-bus

I 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

I 4 MHz reference frequency input: signal from PLL tuning system or operating as

crystal oscillator

I 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

I Precise fully digital Automatic Frequency Control (AFC) detector with 4-bit

digital-to-analog converter, AFC bits readable via I2C-bus

I TakeOver Point (TOP) adjustable via I2C-bus or alternatively with potentiometer

I Fully integrated sound carrier trap for 4.5 MHz, 5.5 MHz, 6.0 MHz and 6.5 MHz,

controlled by FM-PLL oscillator

I Sound IF (SIF) input for single reference Quasi Split Sound (QSS) mode, PLL

controlled

I SIF AGC for gain controlled SIF ampliﬁer, single reference QSS mixer able to operate

in high performance single reference QSS mode and in intercarrier mode, switchable

via I2C-bus

I AM demodulator without extra reference circuit

I Alignment-free selective FM-PLL demodulator with high linearity and low noise

TDA9885; TDA9886
