AK8181E Datasheet 3.3V LVPECL 1:4 Clock Fanout Buffer

Manufacturer: AKM (Asahi Kasei Microdevices)

General Description

The AK8181E is a member of AKM’s LVPECL clock fanout buffer family designed for telecom, networking and computer applications, requiring a range of clocks with high performance and low skew.

The AK8181E distributes 4 buffered clocks.

AK8181E are derived from AKM’s long-termexperienced clock device technology, and enable clock output to perform low skew.

Overview

AK8181E Preliminary 3.3V LVPECL 1:4 Clock Fanout Buffer AK8181E.
