Description

The 8T49N012 is a high-performance clock generator with selectable LVPECL or single-ended outputs. The 8T49N012 can generate selectable frequencies from a crystal or a single-ended reference clock. The frequency is selected from the Frequency Selection Table. Excellent phase noise performance is maintained with Renesas’ fourth-generation FemtoClock™ NG PLL technology.
