KB8527B
INTRODUCTION
KB8527B is a monolithic circuit which can be used in high
performance 60MHz MCA type CLP System.
1 CHIP CLP SUBSYSTEM IC
48 -QFP- 1010E
The KB8527B is a subsystem IC for FM / FSK receiving syste-
ms and a complete one chip FM / FSK receiver IC for 60MHz
system. It`s feature includes receiving functions for FM / FSK
systems, a compandor to remove external noise, and PLL ( Ph-
ase Lock Loop ) of channel selection which blocks surrounding
frequency interference.
The KB8527B can be used with a wide range of FM / FSK VHF
bandwidth systems, including cordless phone, and the narrow
band voice and data sending / receiving systems.
To make applications easily and simply, pheripheral parts are
minimized.
