Description

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.
