Description
The 840N021 is a LVCMOS/LVTTL clock synthesizer designed for Ethernet applications. The device generates a 125MHz clock signal from a 25MHz crystal with excellent phase jitter performance. The device uses Renesas' fourth generation FemtoClock® NG technology for an optimum of high clock frequency, low phase noise performance and low power consumption. It supports 2.5V or 3.3V voltage supply and is packaged in a small, lead-free (RoHS 6) 8-lead TSSOP package. The extended temperature range supports wireless infrastructure, telecommunication, and networking end equipment requirements.
