TDA9881
Datasheet
General description
The TDA9881 is an alignment-free multistandard (PAL and NTSC) vision and sound IF signal PLL demodulator for negative modulation, including Quasi Split Sound (QSS) or intercarrier FM processing.
Features
- 5 V supply voltage
- Gain controlled wideband Vision Intermediate Frequency (VIF) amplifier; AC-coupled
- Multistandard true synchronous demodulation for negative modulated standards with active carrier regeneration: very linear demodulation, good intermodulation figures, reduced harmonics and excellent pulse response
- Fully integrated VIF Voltage Controlled Oscillator (VCO), alignment-free, frequencies switchable via logic pin VIF0 and pin QSSO with resistor
- Digital acquisition help circuit, VIF frequencies of 38.0 MHz, 38.9 MHz, 45.75 MHz 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
- VIF AGC monitor output at pin VAGC
- Precise fully digital Automatic Frequency Control (AFC) detector with 4-bit digital-to-analog converter
- TakeOver Point (TOP) adjustable 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 or in intercarrier mode; switchable via SIF input pins
- Alignment-free selective FM PLL demodulator with high linearity and low noise.
