LV2285VB

www.DataSheet.co.kr Ordering number : ENA1494A Bi-CMOS IC LV2285VB Overview FM transmitter IC with Stereo Modulation, Auto Sleep Function The LV2285VB is IC for FM transmitter. This IC is chiefly composed of the following block. MPX block for stereo modulation, RFVCO block for FM modulation, and PLL block for RF output frequency. At the result, this IC achieves FM transmitter with low power consumption by 1chip. Additionally, the auto sleep function is installed. This function automatically switches the standby and active according to the state of the audio input. It is possible to achieve a more dynamic electric power reduction as a result. Feature The function necessary for FM transmission has been integrated into 1chip. The best low current consumption operation for portable application The auto sleep function to reduce more dynamic current consumption General I2C I/F and, SANYO original audio control I/F is installed Functions Audio: Stereo modulation using pilot tone system, Audio attenuation RF: VCO, programmable gain driver amplifier PLL: 70MHz to 110MHz 100kHz step Bus control: I2C I/F , Audio control I/F Regulator: 2.8V LDO regulator, Auto sleep function Specifications Parameter Maximum Ratings at Ta = 25°C Symbol VCC max Vin max Vin min Pd max Topr Tstg Ta ≤ 85°C, Mounted on a specified board.* Pin 6 Conditions Ratings 7.0 Vcc + 0.3 -0.3 500 -10 to 85 -55 to 150 Unit V V V mW °C °C Maximum supply voltage Maximum input voltage Minimum inp...
