The MPC9446 is a 2.5 V and 3.3 V compatible 1:10 clock distribution buffer designed

for low-voltage mid-range to high-performance telecom, networking and computing

applications. Both 3.3 V, 2.5 V and dual supply voltages are supported for mixed-voltage

applications. The MPC9446 offers 10 low-skew outputs and 2 selectable inputs for clock

redundancy. The outputs are configurable and support 1:1 and 1:2 output to input

frequency ratios. The MPC9446 is specified for the extended temperature range of –40?C

to 85?C.
