Functional Description
Designed for extremely skewed critical differential clock distribution systems, the MC100ES6226 supports clock frequencies from DC to 3.0 GHz. Typical applications of the MC100ES6226 are master clock distribution systems on backplanes for high performance computers, networking and telecommunications systems, and on-board clocks for OC-3, OC-12, and OC-48 speed communication systems.
The MC100ES6226 can operate on a 3.3V or 2.5V positive power supply and does not require a negative power supply. Each output group of the three differential clock output pairs can be configured independently to assign input frequency or half of the input frequency. The FSEL0 and FSEL1 clock frequency selections are asynchronous control inputs. Any change in the control input will require an MR Pulse to resynchronize the ÷2 output.
