NOTICE - The following device(s) are recommended alternatives:
843071I - FemtoClock Crystal-to-3.3V,2.5V LVPECL Clock Generator

Overview

The 843081I-01 is an Ethernet clock multiplier. The 843081I-01 accepts a crystal reference of 19.6MHz - 28MHz. The 843081I-01 has excellent 1ps or lower phase jitter performance, over the 1.875MHz - 20MHz integration range. The 843081I-01 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
