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. Antenna Duplexer
Overview of IDT's single-ended fanout buffers and single-ended fanout dividers. Fanout buffers are a useful building block of many clock trees, providing signal buffering and multiple low-skew copies of the input signal. The clock fanout from a single input reduces loading on the preceding driver and provides an efficient clock distribution network. Presented by Vik Chaudhry, technical marketing manager at IDT.
