PLL FM demodulator for DBS signals

Preliminary specification

TDA8730

FEATURES

• Broadband IF amplifier

• PLL demodulator, consisting of:

– a multiplier

– a voltage controlled oscillator

– a loop amplifier

• AGC detector and DC amplifier

• LOW impedance video and data output

• Power supply voltage stabilizer

GENERAL DESCRIPTION

The TDA8730 is a sensitive PLL

demodulator for the second IF and

direct broadcasting satellite (DBS)

receivers. It provides AGC output and

threshold adjustment for optimal signal

level at the input of the demodulator.
