Product specification
Low power PLL FM demodulator for
satellite TV receivers
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.
APPLICATIONS
• Digital Broadcast System (DBS) satellite receivers.
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.
