Description

KB8527B is a monolithic circuit which can be used in high performance 60MHz MCA type CLP System.

The KB8527B is a subsystem IC for FM / FSK receiving systems 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 ( Phase 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.
