General description

The TDA9884 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.

The device is specially prepared for mobile TV applications.

Features

  • 5 V supply voltage
  • Gain controlled wide-band 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 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 AGC detector for gain control, operating as peak sync detector for negative modulated signals and as a peak white detector for positive modulated signals
  • Mobile mode for negative modulation AGC (VIF and SIF) provides very fast reaction time
  • External AGC setting via pin AGCSW; VIF-AGC and SIF-AGC monitor outputs
  • Precise fully digital AFC detector with 4-bit digital-to-analog converter; AFC bits readable via I2C-bus
  • 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
  • SIF input for single reference QSS mode; PLL controlled
  • True split sound mode for sound demodulation at low RF level
  • 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
  • Four selectable I2C-bus addresses
  • I2C-bus control for all functions
  • I2C-bus transceiver with pin programmable MAD
