1 / 13 page  LMV115 GSM Baseband 30MHz 2.8V Oscillator Buffer General Description The LMV115 is a 30MHz buffer specially designed to mini- mize 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 de- vice is in shutdown mode when the shutdown pin is con- nected to V DD. The LMV115 comes in SC70-6 package. This space saving product reduces components, improves clock signal and allows ease of placement for the best form factor. Features (Typical 2.8V supply; values unless otherwise specified) n Low supply current: 0.3mA n 2.5V to 3.3V supply n AC coupling possible without external bias resistors. n Includes shutdown function external oscillator n SC70-6 pin package 2.1 x 2mm n Operating Temperature Range −40˚C to 85˚C Applications n Cellular phones n GSM Modules n Oscillator Modules Schematic Diagram 20075129 December 2003 © 2003 National Semiconductor Corporation DS200751 www.national.com |
