Product speciﬁcation

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.

GENERAL DESCRIPTION

The TDA9880(T) is an integrated circuit for multistandard

vision IF signal processing and FM demodulation in TV

and VTR sets.
