TDA9880

5V 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,
45.75and 58.75MHz
4MHz 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

detector with 4-bit digital-to-analog converter
Fully integrated sound carrier trap for 4.5,5.5,
6.0and6.5MHz, controlled by reference signal
Alignment-freeselectiveFM-PLLdemodulatorwithhigh linearity and low noise
Digital frequency control, sound carrier frequencies
4.5,5.5,6.0and6.5MHz
Stabilizer circuit for ripple rejection and to achieve
constant output signals
Electrostatic discharge (ESD) protection for all pins.
