LV2283VB
Bi-CMOS IC
FM Transmitter IC with
Stereo Modulation
Overview
The LV2283VB is an FM Transmitter IC. MPX block makes stereo modulated, composite signal from L and R sound
inputs. RF VCO includes FM modulation function. PLL synthesizer determines RF output frequency with I2C control.
Application
• Portable Memory Player
• Portable HDD Player
• Wireless Headphone
Features
• (Audio)
Pilot tone system stereo modulation, audio attenuation
• (RF)
VCO, programmable gain driver amplifier
• (PLL)
70 to 110MHz 100kHz step
• (Bus control) I2C bus control
• (Regulator) 2.8V LDO regulator
