Functional Description The MPC9448 is specifically designed to distribute LV
CMOS 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 serie...
