The CDCM61001 is a highly versatile， low-jitterfrequency synthesizer that can generate low-jitterclock outputs， selectable between low-voltagepositive emitter coupled logic （LVPECL）， low-voltage differential signaling （LVDS）， or low-voltagecomplementary metal oxide semiconductor（LVCMOS） outputs， from a low-frequency crystal orLVCMOS input for a variety of wireline and datacommunication applications. The CDCM61001 features an onboard PLL that can be easilyconfigured solely through control pins. The overall output random jitter performance is less than 1ps，RMS （from 10 kHz to 20 MHz）， making this device aperfect choice for use in demanding applications such as SONET， Ethernet， Fibre Channel， and SAN. TheCDCM61001 is available in a small， 32-pin， 5-mm ×5-mm QFN package.
