Overview
Ordering number : EN4862C Bi CMOS LSI LV3400M FM Multiplex Filter Overview The LV3400M is a filter IC designed for FM multiplex broadcast reception and is used in combination with the Sanyo LC72700 demodulation/error correction IC.
The adoption of switched capacitor (SCF) technology means that frequency adjustment is not required and that the LV3400M provides stable operation.
Package Dimensions unit: mm 3111-MFP14S [LV3400M] Functions • • • • • 76 kHz band-pass filter (Gaussian filter) 54 kHz high-pass filter 125 kHz low-pass filter Anti-aliasing filter Limiter circuit Features • Adjustment-free, due to the use of SCF technology.
• Few external components are required.
