GENERAL DESCRIPTION
The TDA9880(T) is an integrated circuit for multistandard vision IF signal processing and FM demodulation in TV and VTR sets.

FEATURES
• 5 V supply voltage
• Gain controlled wide-band Vision Intermediate Frequency (VIF) amplifier (AC-coupled)
• True synchronous demodulation 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
• Digital acquisition help, VIF frequencies of 38.0, 38.9, 45.75 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, fast reaction time
• Precise fully digital Automatic Frequency Control (AFC) detector with 4-bit digital-to-analog converter
• Fully integrated sound carrier trap for 4.5, 5.5, 6.0 and 6.5 MHz, controlled by reference signal
• Alignment-free selective FM-PLL demodulator with high linearity and low noise
• Digital frequency control, sound carrier frequencies 4.5, 5.5, 6.0 and 6.5 MHz
• Stabilizer circuit for ripple rejection and to achieve constant output signals
• Electrostatic discharge (ESD) protection for all pins.
