843001I-23 - Block Diagram
Description
The 843001I-23 is a highly versatile, low phase noise LVPECL/LVCMOS synthesizer that can generate low jitter reference clocks for a variety of communication applications. The dual crystal interface allows the synthesizer to support up to three communication standards in a given application (i.e. SONET with a 19.44MHz crystal, 1Gb/10Gb Ethernet and Fibre Channel using a 25MHz 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, GbE/10Gb Ethernet and SAN applications. The 843001I-23 is packaged in a small 24-pin TSSOP, E-Pad package.
