The CDCE18005 is a high performance clock distributor featuring a high degree of configurability via a SPI interface, and programmable start up modes determined by on-chip 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⁾

Universal Input Buffers That Accept LVPECL, LVDS, or LVCMOS Level Signaling
Fully Configurable Outputs Including Frequency, Output Format, and Output Skew
Output Multiplexer That Serves as a Clock Switch Between the Three Reference Inputs
and the Outputs
Clock Generation Via AT-Cut Crystal
Integrated EEPROM Determines Device Configuration at Power-up
Low Additive Jitter Performance
Universal Output Blocks Support up to 5 Differential, 10 Single-ended, or
Combinations of Differential or Single-ended:
