Preliminary specification
PLL FM demodulator for DBS signals
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.
