Description
The AK8181A 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 AK8181A distributes 4 buffered
clocks.
AK8181A are derived from AKM’ｓ long-term-
experienced clock device technology, and enable
clock output to perform low skew. The AK8181A
is available in a 20-pin TSSOP package.
