Description
The AK8181C 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 AK8181C distributes 2 buffered
clocks.
AK8181C are derived from AKM’ｓ long-term-
experienced clock device technology, and enable
clock output to perform low skew. The AK8181C
is available in a 14-pin TSSOP package.
