Renesas clock dividers (clock frequency dividers) provide an output clock signal that is a divided frequency of the input. They can also be used as clock buffers and make multiple copies of the output frequency. Clock divider devices, when used in divide-by-1 mode, can also function as a fanout buffer.
The Renesas "8" series of fanout buffers and clock dividers feature fully differential internal architecture, even devices with single-ended I/Os. This improves jitter due to inherent common-mode noise rejection and improves output skew. The differential circuitry is constant-current and therefore injects less noise into system power supplies than single-ended solutions, reducing EMI compliance concerns.
