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.

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
