3 V Operation Filter for FM Multiplex
Broadcasting Reception
Overview
The LV3403M is a filter IC for FM multiplex broadcasting
reception which is used in combination with demodulation-
error correction IC (LC72703). The use of switched capacitor
filter (SCF) technique obviates the need for frequency
adjustment and ensures stable operation.
