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.

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.
