Wideband PLL FM Demodulator

The SL1466 is a wideband PLL FM demodulator, intended primarily for application in satellite tuners.

The device contains all elements necessary, with the exception of external local oscillator tank and loop filter components, to form a complete PLL system operating at 403 or 480MHz.

An AFC system is provided, whose output signals can be used to correct for any frequency drift at the head end local oscillator.

FEATURES

■ Single chip PLL system for wideband FM demodulation
