Description
The AK8180C is a member of AKM’ｓ LVCMOS
clock fanout buffer family designed for telecom,
networking and computer applications, requiring a
range of clocks with high performance and low
skew. The AK8180C distributes 12 buffered
clocks up to 350MHz. The 12 outputs can drive
terminated 50  clock lines. The CLK_STOP
control allows the output signal to start and stop
only in a logic low state. The OE control sets the
outputs to high-impedance mode.
AK8180C are derived from AKM’ｓ long-term-
experienced clock device technology, and enable
clock output to perform low skew. The AK8180C is
available in a 7mm x 7mm 32-pin LQFP package.
