LV2282VA
FM Transmitter IC with
Stereo Modulation
Overview
The LV2282VA is an FM Transmitter IC. MPX block makes stereo modulated, composite signal from L and R sound
inputs. RF VCO include FM modulation function. Audio AGC function keeps FM modulation well regulated. PLL
synthesizer determines RF output frequency with I2C or 3-bit parallel control (selectable).
