844N255I Description
The 844N255I is a 6-output clock synthesizer designed for wireless infrastructure clock applications. The device uses IDT’s fourth generation FemtoClock® NG technology for an optimum of high clock frequency and low phase noise performance, bined with a low power consumption and high power supply noise rejection. The reference frequency is selectable and the following frequency is supported:.
