SL1461, Wideband PLL FM Demodulator

The SL1461SA is a wideband PLL FM demodulator, optimised for application in satellite receiver systems and requiring a minimum external component count.

It contains all the elements required for construction of a phase locked loop circuit, with the exception of tuning components for the local oscill

SL1461SA Wideband PLL FM Demodulator Advance Information DS4049 - 1.2 December 1994 The SL1461SA is a wideband PLL FM demodulator, intended primarily for application in satellite tuners.

The device contains all elements necessary, with the exception of external oscillator sustaining network and loop feedback components, to form a complete PLL system operating at frequencies up to 800MHz.

An AFC with window adjust is provided, whose output signal can be used to correct for any frequency drift at
