PS20100 - Plessey Semiconductors

PS20100 Wideband PLL FM Demodulator

The PS20100 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 oscillator, and an AFC detector circuit for generation of error sig.
