WIDEBAND PLL FM
DEMODULAT OR
DES CRIPT ION
As a wideband PLL FM demodulator, the UTC L2572 is
intended for application in satellite tuners primarily.
The device includes all the necessary elements, with
external oscillator sustaining network and the exception of
loop feedback components, to form a PLL system operating
at frequencies up to 800MHz completely.
An AFC with window adjust (whose output signal can be
used to correct for any frequency drift at the head end local
oscillator) is provided.
FEAT URES
