时钟和时序

当今计算系统的各种接口（PCI Express、SATA、USB、SAS、DMI、QPI、超传输、以太网等）和多种 CPU 架构（Intel、Freescale 等）要求在性能、BOM 成本和电路板空间方面进行一系列复杂的权衡。 DT 与业内领先的 CPU 和计算供应商拥有最长的稳定关系，可提供最大的参考时钟解决方案和增值时钟产品组合，从而实现最佳权衡。

Renesas 是计算计时空间方面的领先创新者，拥有多个第一，其中包括：第一次引进替代标准 HCSL 的低功耗 HCSL 输出，节能比例高达 85%；第一次提供动态频率控制来控制超频/低频；第一次在单个器件中采用多个 PLL 来节省能源和电路板空间。 Renesas 提供最适合特定设计的主板时钟和服务器时钟解决方案。 浏览下面所列出的器件，查找理想的计算时钟解决方案。

    Parametric Table tips

    Tips for Using This Parametric Table:

    • Hide Filters button in header: Collapse or expands filters
    • Column sort buttons in header: Sort Column alphabetically / numerically descending or ascending
    • Reset button in header: Reset all filters to the page default
    • Full Screen button in header: Expand the table to full screen view (user must close out of full screen before they can interact with rest of page)
    • Export button in header: Export the filtered results of the table to an Excel document
    • Filter parts search bar in header: Type to filter table results by part number
    • Hide column button in column headers: Select to hide columns in table
    • AND / OR toggle switches in header: Toggles the logic of this particular filter to be “AND” or “OR” logic for filtering results
    • Multiselect checkboxes at beginning of each row in table: Select these checkboxes to compare products against each other
    • Document icon next to product name in row: View the featured document for this product
    • Chip icon next to the right of the document icon in row: View the block diagram for this product
    • Cart icon to the right of the chip icon: Indicates that samples are available for this product
