DESCRIPTION  
Integrated EEPROM Determines Device  
Configuration at Power-up  
The CDCE18005 is  
a high performance clock  
generator and distributor featuring a high degree of  
configurability via a SPI interface, and programmable  
start up modes determined by on-board EEPROM.  
Specifically tailored for buffering clocks for data  
converters and high-speed digital signals, the  
CDCE18005 achieves low additive jitter in the 50 fs  
RMS(1) range. The clock distribution block includes  
five individually programmable outputs that can be  
configured to provide different combinations of output  
formats (LVPECL, LVDS, LVCMOS). Each output can  
also be programmed to a unique output frequency  
(up to 1.5 GHz(2) ) and skew relationship via a  
programmable delay block. If all outputs are  
configured in single-ended mode (e.g. LVCMOS), the  
CDCE18005 supports up to ten outputs. Each output  
can select one of three clock input sources. The input  
block includes two universal differential inputs which  
support frequencies up to 1500 MHz and an auxiliary  
single ended input that can be connected to a CMOS  
level clock or configured to connect to an external  
crystal via an on board oscillator block.
