The MPC9448 is specifically designed to distribute LVCMOS compatible clock signals up to a frequency of 350 MHz.
Each output provides a precise copy of the input signal with a near zero skew.
The outputs buffers support driving of 50Ω terminated transmission lines on the incident edge: each output is capable of driving either one parallel terminated or two series terminated transmission lines.
