CDCE18005 - Three Input / Ten Output Mixed Mode Clock Buffer - 通用（可编程） - 时钟缓冲器 - TI公司（Texas Instruments，德州仪器）
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)
