SL1466

Wideband PLL FM Demodulator

Preliminary Information

DS 3979 2.2 August 1997

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.
