satellite TV receivers

Product specification

TDA8012AM

FEATURES

• High input sensitivity

• Fully balanced two-pin Voltage Controlled Oscillator

(VCO)

• Low input impedance (50 Ω)

• Low impedance video baseband output

• Internal voltage stabilizer

• Keyed Automatic Frequency Control (AFC) or peak AFC

• Carrier detector

• Automatic Gain Control (AGC) output.

GENERAL DESCRIPTION

The TDA8012AM is a sensitive Phase Locked Loop (PLL)

Frequency Modulation (FM) demodulator for the second

Intermediate Frequency (IF) in satellite receivers.

It provides Automatic Gain Control (AGC) and Automatic

Frequency Control (AFC) outputs that can be used to

optimize the level and the frequency of the signal applied

at the input. During the search procedure, the AFC output

provides a signal used for carrier detection.

APPLICATIONS

• Digital Broadcast System (DBS) satellite receivers.
