840002AGI-01LFT

Clock Generators, PLLs, Frequency Synthesizers Overview

The Renesas 840002AGI-01LFT is a FemtoClock ultra-low jitter frequency synthesizer designed for crystal-to-LVCMOS/LVTTL applications. It utilizes third-generation low phase noise VCO technology to achieve typical random RMS phase jitter of 1ps or lower. The device features two LVCMOS/LVTTL outputs and is optimized for generating Ethernet reference clock frequencies when paired with a 25MHz 18pF parallel resonant crystal. It operates at a maximum output frequency of 175MHz and is housed in a 16-TSSOP package measuring 5.0 x 4.4 x 1.0 mm.
