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)

CDCE18005EVM — CDCE18005EVM 评估模块

CDCE18005 是高性能时钟发生器和分配器，它具有高度可配置性（通过 SPI 接口进行配置）和由片上 EEPROM 确定的可编程启动模式。专为数据转换器和高速数字信号的缓冲时钟而设计，CDCE18005 实现了 50 fs 范围以内的低附加抖动。时钟分配块包含 5 个独立的可编程输出，它们可以配置成提供不同的输出格式组合（LVPECL、LVDS、LVCMOS）。也可以通过可编程延迟块将每个输出编程为独特的输出频率（高达 1.5GHzGHz）和偏移关系。如果所有输出都采用单端模式（例如 LVCMOS）进行配置，则 CDCE18005 可支持多达 10 路输出。每个输出都可以选择 3 (...)
