Description
The AK8180A 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 AK8180A distributes 10 buffered clocks
configured by pin-setting per bank. Each bank has
the selected output divided by one or two through
DSELx pin. Each of 3-bank outputs operate at
2.5V or 3.3V respectively. The 10 outputs can
drive terminated 50 W transmission lines.
The AK8180A is available in a 7mm x 7mm 32-pin
LQFP package.
