GENERAL DESCRIPTION
The TDA8012M is a sensitive PLL FM demodulator which is used for the second 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 frequency of the input signal. During the searching procedure, the AFC output provides a signal which is 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 AFC or peak-to-peak AFC
• Carrier detector
• AGC output
• Suitable for High Definition TV (HDTV).
APPLICATIONS
• Direct Broadcast Satellite (DBS) receivers.
