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

■ 5 V supply voltage

■ Gain controlled wideband 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 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 amplifier, 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
