for satellite TV receivers

Product specification

TDA8012M

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.

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.
