Description

The MEO-0801A is a ultra high speed clock divider based on a 0.8 µm SiGe-HBT process. It consist of a differential input amplifier, a programmable divider and output buffers. The device is prepared for working in a 50 W environment. The device provides a differential input and differential outputs. All ports can be used for single ended operations matched to 50 W environment.

The divider based on asynchronous switched flip-flops. The divider output is resynchronised to the input clock.

It is available mounted on a thin film carrier.
