LV3403M

Ordering number: EN5191A Bi-CMOS LSI LV3403M 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 demodulationerror correction IC (LC72703). The use of switched capacitor filter (SCF) technique obviates the need for frequency adjustment and ensures stable operation.

Common for SCF section. Connect to decoupling capacitor. Signal input. Input a frequency-modulated signal (composite signal) at 200 to 300 mVrms. When inputting 76 kHz only, the input sensitivity is 4 mVrms or less. MSK output (CMOS output.) Limiter reference pin. Form an LPF with the 10 kΩ internal resistor and an external capacitor. 3.6 MHz clock input. Because the DC bias is output by the limiter amplifier input, the clock is input with capacitor coupling. Power supply Test pin. Leave open. Unused. Description Notes on usage: (1) When using this IC, leave pins 4 to 9 and pin 13 open. (2) The clock is connected to pin 12 from the decoder (LC72700) clock output pin through a 100 pF capacitor. In addition, by inserting a resistor in the clock line, it is possible to dampen the rising and falling edges, reducing spurious radiation.
