Audio Oversampling Clock Generator 8-Pin SOIC N T/R

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.
