MARKING

Description

The NB3N3010B is a precision, low noise clock multiplier that

generates an output frequency of 12.288 MHz. This is accomplished

by using Frequency−Locked−Loop (FLL) techniques where a 4 kHz

reference input is multiplied by 3072, or an 8 kHz input by 1536. The

frequency multiplier is selected by the S0 pin.

The two LVCMOS output drivers are disabled to a logic Low with

the ENABLEn pin set HIGH. The NB3N3010B operates from a single

+3.3 V supply, and is available in the SOIC−8 pin package, and

optionally in a DFN8 package. The operating temperature range is

from 0°C to +85°C.

The NB3N3010B device provides the optimum combination of low

cost, flexibility, and high performance. This makes it ideal for

applications such as oversampling A−to−D and D−to−A converters

from a low reference frequency, such as a USB start−of−frame (SOF)

pulse.
