8T49N006A-055NLGI

Overview

The 8T49N006A-055NLGI is a programmable clock generator from the FemtoClock NG series by Renesas Electronics Corporation. It features six selectable LVPECL or LVDS outputs and utilizes fourth-generation PLL technology for low phase jitter performance. The device operates on a single supply voltage ranging from 2.375V to 3.465V and supports an input frequency range up to 312.5MHz. Designed for surface mount applications, it is housed in a 48-VFQFN exposed pad package with dimensions of 7x7mm. The component functions as a frequency synthesizer capable of generating multiple output frequencies from a single crystal or reference clock input.
