NJW2307

NJW2307 FM Modulation/Demodulation with PLL  GENERAL DESCRIPTION NJW2307 is a FM modulation / demodulation IC for audio signal in full duplex communication that operates from 3.8V. In addition to audio signal, it can also be used in data pulse. By the parallel interface, set the carrier frequency (2.3MHz / 2.8MHz), and allows independently power-down control the Modulation / Demodulation circuit. The NJW2307 includes FM Modulation / Demodulation, VCO, PLL and AFC, will contribute to the adjustment-free.  PACKAGE OUTLINE NJW2307VC3  APPLICATIONS Interphone, Voice for Hot water supply system , Wireless and Wired Communication Systems  FEATURES  Operating Voltage 3.8 to 5.5V  Low operating Current Mod : 9mA typ.
