Clocks & Timing

Renesas clock generators and synthesizers are all PLL-based products that generate one or more clock signals within an application. This category contains low jitter clock generators suitable for serial data applications up to 100G. Many other applications, such as PCIe, have separate pages under Application-Specific Clocks. If more than one unique output frequency is required (e.g. 100MHz and 125MHz), make use of the “Output Banks” parametric selector. Each bank corresponds to a unique output frequency. The number of outputs per bank is highly variable depending on the clock generator.

Once the clock generator is selected, fanout buffers can be used to provide additional copies and types (LVCMOS, LVPECL, etc) of outputs. Renesas has the largest selection of timing products in the industry, which allows for highly optimized solutions.
