The NB3U1548C is an LVCMOS, overvoltage tolerant clock fanoutbuffer targeted for clock generation in high performancetelecommunication, networking and computing applications. Thedevice is optimized for low skew clock distribution in low voltageapplications. The input overvoltage tolerance enables using thisdevice in mixed mode voltage applications. An output enable pincontrols whether the outputs are in the active or high impedance state.Guaranteed output skew characteristics make the NB3U1548C idealfor those applications demanding well defined performance andrepeatability. The NB3U1548C is packaged in a small SOIC−8 and inan TSSOP−8 package.
