描述

The 843001I-22 is a highly versatile, low phase noise LVPECL/LVCMOS Synthesizer that can generate low jitter reference clocks for a variety of communications applications. The dual crystal interface allows the synthesizer to support up to two communication standards in a given application (i.e. 1GB Ethernet with a 25MHz crystal and 1Gb Fibre Channel using a 26.5625MHz crystal). The rms phase jitter performance is typically less than 1ps, thus making the device acceptable for use in demanding applications such as OC48 SONET and 10Gb Ethernet. The 843001I-22 is packaged in a small 24-pin TSSOP package.
