LMV115 - GSM Baseband 30MHz 2.8V Oscillator Buffer

General Description

The LMV115 is a 30MHz buffer specially designed to minimize the effects of spurious signals from the base band chip to the oscillator.

The buffer also minimizes the influence of varying load resistance and capacitance to the oscillator and increases the drive capability.

LMV115 GSM Baseband 30MHz 2.8V Oscillator Buffer December 2003 LMV115 GSM Baseband 30MHz 2.8V Oscillator Buffer General Description The LMV115 is a 30MHz buffer specially designed to minimize the effects of spurious signals from the base band chip to the oscillator. The buffer also minimizes the influence of varying load resistance and capacitance to the oscillator and increases the drive capability. The input of the LMV115 is internally biased with two equal resistors to the power supply rails. This allows AC coupling on the input. The LMV115 offers a shutdown function to optimize current consumption. This shutdown function can also be used to control the supply voltage of an external oscillator. The device is in shutdown mode when the shutdown pin is connected to VDD.
