Product specication
Alignment-free multistandard vision and
FM sound IF-PLL demodulator
TDA9880
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.
