description  
The CDC7005 is a high-performance, low-phase noise, and low-skew clock synthesizer and jitter cleaner that  
synchronizes the voltage controlled crystal oscillator (VCXO) frequency to the reference clock. The  
programmable predividers M and N give a high flexibility to the frequency ratio of the reference clock to VCXO:  
VCXO_IN/REF_IN = (NxP)/M. The VCXO_IN clock operates up to 800 MHz. Through the selection of external  
VCXO and loop filter components, the PLL loop bandwidth and damping factor can be adjusted to meet different  
system requirements. Each of the five differential LVPECL outputs are programmable by the serial peripheral  
interface (SPI). The SPI allows individual control of frequency and enable/disable state of each output. The  
device operates in 3.3-V environment. The built-in latches ensure that all outputs are synchronized.  
The CDC7005 is characterized for operation from –40°C to 85°C.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
