LMV115

GSM Baseband 30MHz 2.8V Oscillator Buffer

General Description

Features

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.

(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

The input of the LMV115 is internally biased with two equal

resistors to the power supply rails. This allows AC coupling

on the input.

n Operating Temperature Range −40˚C to 85˚C

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-

Applications

n Cellular phones

n GSM Modules

nected to V_DD

n Oscillator Modules

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.
